FLEx36TM 3.3V 32K/64K/128K/256K/512 x 36
Synchronous Dual-Port RAM
Features
Functional Description
• True dual-ported memory cells that allow simultaneous
access of the same memory location
The FLEx36 family includes 1-Mbit, 2-Mbit, 4-Mbit, 9-Mbit and
18-Mbit pipelined, synchronous, true dual-port static RAMs
that are high-speed, low-power 3.3V CMOS. Two ports are
provided, permitting independent, simultaneous access to any
location in memory. A particular port can write to a certain
location while another port is reading that location. The result
of writing to the same location by more than one port at the
same time is undefined. Registers on control, address, and
data lines allow for minimal set-up and hold time.
• Synchronous pipelined operation
• Family of 1-Mbit, 2-Mbit, 4-Mbit, 9-Mbit and 18-Mbit
devices
• Pipelined output mode allows fast operation
• 0.18-micron CMOS for optimum speed and power
• High-speed clock to data access
During a Read operation, data is registered for decreased
cycle time. Each port contains a burst counter on the input
address register. After externally loading the counter with the
initial address, the counter will increment the address internally (more details to follow). The internal Write pulse width is
independent of the duration of the R/W input signal. The
internal Write pulse is self-timed to allow the shortest possible
cycle times.
• 3.3V low power
— Active as low as 225 mA (typ.)
— Standby as low as 55 mA (typ.)
• Mailbox function for message passing
• Global master reset
• Separate byte enables on both ports
A HIGH on CE0 or LOW on CE1 for one clock cycle will power
down the internal circuitry to reduce the static power
consumption. One cycle with chip enables asserted is required
to reactivate the outputs.
• Commercial and industrial temperature ranges
• IEEE 1149.1-compatible JTAG boundary scan
• 256-ball FBGA (1-mm pitch)
Additional features include: readback of burst-counter internal
address value on address lines, counter-mask registers to
control the counter wrap-around, counter interrupt (CNTINT)
flags, readback of mask register value on address lines,
retransmit functionality, interrupt flags for message passing,
JTAG for boundary scan, and asynchronous Master Reset
(MRST).
• Counter wrap around control
— Internal mask register controls counter wrap-around
— Counter-interrupt flags to indicate wrap-around
— Memory block retransmit operation
• Counter readback on address lines
The CYD18S36V devices in this family has limited features.
Please see Address Counter and Mask Register Operations[18] on page 5 for details.
• Mask register readback on address lines
• Dual Chip Enables on both ports for easy depth
expansion
Seamless Migration to Next-Generation Dual-Port Family
• Seamless migration to next-generation dual-port family
Cypress offers a migration path for all devices in this family to
the next-generation devices in the Dual-Port family with a
compatible footprint. Please contact Cypress Sales for more

Master Reset
The FLEx36 family devices undergo a complete reset by
taking its MRST input LOW. The MRST input can switch
asynchronously to the clocks. An MRST initializes the internal
burst counters to zero, and the counter mask registers to all
ones (completely unmasked). MRST also forces the Mailbox
Interrupt (INT) flags and the Counter Interrupt (CNTINT) flags
HIGH. MRST must be performed on the FLEx36 family
devices after power-up.
Mailbox Interrupts
The upper two memory locations may be used for message
passing and permit communications between ports. Table 2
shows the interrupt operation for both ports of CYD18S36V.
The highest memory location, 7FFFF is the mailbox for the
right port and 7FFFE is the mailbox for the left port. Table 2
shows that in order to set the INTR flag, a Write operation by
the left port to address 7FFFF will assert INTR LOW. At least
one byte has to be active for a Write to generate an interrupt.
A valid Read of the 7FFFF location by the right port will reset
INTR HIGH. At least one byte has to be active in order for a
Read to reset the interrupt. When one port Writes to the other
port’s mailbox, the INT of the port that the mailbox belongs to
is asserted LOW. The INT is reset when the owner (port) of the
mailbox Reads the contents of the mailbox. The interrupt flag
is set in a flow-thru mode (i.e., it follows the clock edge of the
writing port). Also, the flag is reset in a flow-thru mode (i.e., it
follows the clock edge of the reading port).
Each port can read the other port’s mailbox without resetting
the interrupt. And each port can write to its own mailbox
without setting the interrupt. If an application does not require
message passing, INT pins should be left open.

Address Counter and Mask Register
Operations[18]
This section describes the features only apply to 1Mbit, 2 Mbit,
4 Mbit and 9 Mbit devices. It does not apply to 18Mbit device.
Each port of these devices has a programmable burst address
counter. The burst counter contains three registers: a counter
register, a mask register, and a mirror register.
The counter register contains the address used to access the
RAM array. It is changed only by the Counter Load, Increment,
Counter Reset, and by master reset (MRST) operations.
The mask register value affects the Increment and Counter
Reset operations by preventing the corresponding bits of the
counter register from changing. It also affects the counter
interrupt output (CNTINT). The mask register is changed only
by the Mask Load and Mask Reset operations, and by the
MRST. The mask register defines the counting range of the
counter register. It divides the counter register into two
regions: zero or more “0s” in the most significant bits define
the masked region, one or more “1s” in the least significant bits
define the unmasked region. Bit 0 may also be “0,” masking
the least significant counter bit and causing the counter to
increment by two instead of one.
The mirror register is used to reload the counter register on
increment operations (see “retransmit,” below). It always
contains the value last loaded into the counter register, and is
changed only by the Counter Load, and Counter Reset operations, and by the MRST.
Notes:
13. CE is internal signal. CE = LOW if CE0 = LOW and CE1 = HIGH. For a single Read operation, CE only needs to be asserted once at the rising edge of the CLK
and can be deasserted after that. Data will be out after the following CLK edge and will be three-stated after the next CLK edge.
14. OE is “Don’t Care” for mailbox operation.
15. At least one of BE0, BE1, BE2, or BE3 must be LOW.
16. A17x is a NC for CYD04S36V, therefore the Interrupt Addresses are 1FFFF and 1FFFE. A17x and A16x are NC for CYD02S36V, therefore the Interrupt Addresses
are FFFF and FFFE; A17x, A16x and A15x are NC for CYD01S36V, therefore the Interrupt Addresses are 7FFF and 7FFE.
17. “X” = “Don’t Care,” “H” = HIGH, “L” = LOW.

PRELIMINARY
Table 3 summarizes the operation of these registers and the
required input control signals. The MRST control signal is
asynchronous. All the other control signals in Table 3
(CNT/MSK, CNTRST, ADS, CNTEN) are synchronized to the
port’s CLK. All these counter and mask operations are
independent of the port’s chip enable inputs (CE0 and CE1).
Counter enable (CNTEN) inputs are provided to stall the
operation of the address input and utilize the internal address
generated by the internal counter for fast, interleaved memory
applications. A port’s burst counter is loaded when the port’s
address strobe (ADS) and CNTEN signals are LOW. When the
port’s CNTEN is asserted and the ADS is deasserted, the
address counter will increment on each LOW to HIGH
transition of that port’s clock signal. This will Read/Write one
word from/into each successive address location until CNTEN
CYD01S36V
CYD02S36V/CYD04S36V
CYD09S36V/CYD18S36V
is deasserted. The counter can address the entire memory
array, and will loop back to the start. Counter reset (CNTRST)
is used to reset the unmasked portion of the burst counter to
0s. A counter-mask register is used to control the counter
wrap.
Counter Reset Operation
All unmasked bits of the counter and mirror registers are reset
to “0.” All masked bits remain unchanged. A Mask Reset
followed by a Counter Reset will reset the counter and mirror
registers to 00000, as will master reset (MRST).
Counter Load Operation
The address counter and mirror registers are both loaded with
the address value presented at the address lines.

valid tCA2 after the next rising edge of the port’s clock. If
address readback occurs while the port is enabled (CE0 LOW
and CE1 HIGH), the data lines (DQs) will be three-stated.
Figure 1 shows a block diagram of the operation.
Once the address counter register is initially loaded with an
external address, the counter can internally increment the
address value, potentially addressing the entire memory array.
Only the unmasked bits of the counter register are incremented. The corresponding bit in the mask register must be
a “1” for a counter bit to change. The counter register is incremented by 1 if the least significant bit is unmasked, and by 2
if it is masked. If all unmasked bits are “1,” the next increment
will wrap the counter back to the initially loaded value. If an
Increment results in all the unmasked bits of the counter being
“1s,” a counter interrupt flag (CNTINT) is asserted. The next
Increment will return the counter register to its initial value,
which was stored in the mirror register. The counter address
can instead be forced to loop to 00000 by externally
connecting CNTINT to CNTRST.[20] An increment that results
in one or more of the unmasked bits of the counter being “0”
will de-assert the counter interrupt flag. The example in
Figure 2 shows the counter mask register loaded with a mask
value of 0003Fh unmasking the first 6 bits with bit “0” as the
LSB and bit “16” as the MSB. The maximum value the mask
register can be loaded with is 3FFFFh. Setting the mask
register to this value allows the counter to access the entire
memory space. The address counter is then loaded with an
initial value of 8h. The base address bits (in this case, the 6th
address through the 16th address) are loaded with an address
value but do not increment once the counter is configured for
increment operation. The counter address will start at address
8h. The counter will increment its internal address value till it
reaches the mask register value of 3Fh. The counter wraps
around the memory block to location 8h at the next count.
CNTINT is issued when the counter reaches its maximum
value.
The mask register is loaded with the address value presented
at the address lines. Not all values permit correct increment
operations. Permitted values are of the form 2n – 1 or 2n – 2.
From the most significant bit to the least significant bit,
permitted values have zero or more “0s,” one or more “1s,” or
one “0.” Thus 7FFFF, 003FE, and 00001 are permitted values,
but 7F0FF, 003FC, and 00000 are not.
Counter Hold Operation
Mask Readback Operation
The value of all three registers can be constantly maintained
unchanged for an unlimited number of clock cycles. Such
operation is useful in applications where wait states are
needed, or when address is available a few cycles ahead of
data in a shared bus interface.
The internal value of the mask register can be read out on the
address lines. Readback is pipelined; the address will be valid
tCM2 after the next rising edge of the port’s clock. If mask
readback occurs while the port is enabled (CE0 LOW and CE1
HIGH), the data lines (DQs) will be three-stated. Figure 1
shows a block diagram of the operation.
Counter Interrupt
The counter interrupt (CNTINT) is asserted LOW when an
increment operation results in the unmasked portion of the
counter register being all “1s.” It is deasserted HIGH when an
Increment operation results in any other value. It is also
de-asserted by Counter Reset, Counter Load, Mask Reset
and Mask Load operations, and by MRST.
Counter Readback Operation
The internal value of the counter register can be read out on
the address lines. Readback is pipelined; the address will be
Retransmit
Retransmit is a feature that allows the Read of a block of
memory more than once without the need to reload the initial
address. This eliminates the need for external logic to store
and route data. It also reduces the complexity of the system
design and saves board space. An internal “mirror register” is
used to store the initially loaded address counter value. When
the counter unmasked portion reaches its maximum value set
by the mask register, it wraps back to the initial value stored in
this “mirror register.” If the counter is continuously configured
in increment mode, it increments again to its maximum value
and wraps back to the value initially stored into the “mirror
register.” Thus, the repeated access of the same data is
allowed without the need for any external logic.
Mask Reset Operation
The mask register is reset to all “1s,” which unmasks every bit
of the counter. Master reset (MRST) also resets the mask
register to all “1s.”
Mask Load Operation
Counting by Two
When the least significant bit of the mask register is “0,” the
counter increments by two. This may be used to connect the
x36 devices as a 72-bit single port SRAM in which the counter
of one port counts even addresses and the counter of the other
port counts odd addresses. This even-odd address scheme
stores one half of the 72-bit data in even memory locations,
and the other half in odd memory locations.
Note:
20. CNTINT and CNTRST specs are guaranteed by design to operate properly at speed grade operating frequency when tied together.

IEEE 1149.1 Serial Boundary Scan (JTAG)[22]
The FLEx36 family devices incorporate an IEEE 1149.1 serial
boundary scan test access port (TAP). The TAP controller
functions in a manner that does not conflict with the operation
of other devices using 1149.1-compliant TAPs. The TAP
operates using JEDEC-standard 3.3V I/O logic levels. It is
composed of three input connections and one output
connection required by the test logic defined by the standard.
Performing a TAP Reset
A reset is performed by forcing TMS HIGH (VDD) for five rising
edges of TCK. This reset does not affect the operation of the
devices, and may be performed while the device is operating.
An MRST must be performed on the devices after power-up.
Performing a Pause/Restart
When a SHIFT-DR PAUSE-DR SHIFT-DR is performed the
scan chain will output the next bit in the chain twice. For
example, if the value expected from the chain is 1010101, the
device will output a 11010101. This extra bit will cause some
testers to report an erroneous failure for the devices in a scan
test. Therefore the tester should be configured to never enter
the PAUSE-DR state.
Boundary Scan Hierarchy for 9-Mbit and 18-Mbit Devices
Internally, the devices have multiple DIEs. Each DIE contains
all the circuitry required to support boundary scan testing. The
circuitry includes the TAP, TAP controller, instruction register,
and data registers. The circuity and operation of the DIE
boundary scan are described in detail below.
The scan chain for 9-Mbit and 18-Mbit devices uses a hierarchical approach as shown in Figure 3 and Figure 4. TMS and
TCK are connected in parallel to each DIE to drive all 2- or
4-TAP controllers in unison. In many cases, each DIE will be
supplied with the same instruction. In other cases, it might be
useful to supply different instructions to each DIE. One
example would be testing the device ID of one DIE while
bypassing the rest.
Each pin of the devices is typically connected to multiple DIEs.
For connectivity testing with the EXTEST instruction, it is
desirable to check the internal connections between DIEs as
well as the external connections to the package. This can be
accomplished by merging the netlist of the devices with the
netlist of the user’s circuit board. To facilitate boundary scan
testing of the devices, Cypress provides the BSDL file for each
DIE, the internal netlist of the device, and a description of the
device scan chain. The user can use these materials to easily
integrate the devices into the board’s boundary scan
environment. Further information can be found in the Cypress
application note Using JTAG Boundary Scan For System in a
Package (SIP) Dual-Port SRAMs.
Notes:
21. The “X” in this diagram represents the counter upper bits.
22. Boundary scan is IEEE 1149.1-compatible. See “Performing a Pause/Restart” for deviation from strict 1149.1 compliance.

Notes:
36. In this depth-expansion example, B1 represents Bank #1 and B2 is Bank #2; each bank consists of one Cypress FLEx36 device from this data sheet. ADDRESS(B1)
= ADDRESS(B2).
37. ADS = CNTEN= BE0 – BE3 = OE = LOW; MRST = CNTRST = CNT/MSK = HIGH.
38. Output state (HIGH, LOW, or high-impedance) is determined by the previous cycle control signals.
39. During “No Operation,” data in memory at the selected address may be corrupted and should be rewritten to ensure data integrity.
40. CE0 = OE = BE0 – BE3 = LOW; CE1 = R/W = CNTRST = MRST = HIGH.
41. CE0 = BE0 – BE3 = R/W = LOW; CE1 = CNTRST = MRST = CNT/MSK = HIGH. When R/W first switches low, since OE = LOW, the Write operation cannot be
completed (labelled as no operation). One clock cycle is required to three-state the I/O for the Write operation on the next rising edge of CLK.

49. This timing is valid when one port is writing, and other port is reading the same location at the same time. If tCCS is violated, indeterminate data will be Read out.
50. If tCCS < minimum specified value, then R_Port will Read the most recent data (written by L_Port) only (2 * tCYC2 + tCD2) after the rising edge of R_Port's clock. If
tCCS > minimum specified value, then R_Port will Read the most recent data (written by L_Port) (tCYC2 + tCD2) after the rising edge of R_Port's clock.

Notes:
56. CE0 = OE = ADS = CNTEN = LOW; CE1 = CNTRST = MRST = CNT/MSK = HIGH.
57. Address “7FFFF” is the mailbox location for R_Port of the 9-Mbit device.
58. L_Port is configured for Write operation, and R_Port is configured for Read operation.
59. At least one byte enable (BE0 – BE3) is required to be active during interrupt operations.
60. Interrupt flag is set with respect to the rising edge of the Write clock, and is reset with respect to the rising edge of the Read clock.
61. OE is an asynchronous input signal.
62. When CE changes state, deselection and Read happen after one cycle of latency.
63. CE0 = OE = LOW; CE1 = R/W = HIGH.
