Description
The CXK79M72C160GB (organized as 262,144 words by 72 bits), CXK79M36C160GB (organized as 524,288 words by 36
bits), and the CXK79M18C160GB (organized as 1,048,576 words by 18 bits) are high speed CMOS synchronous static RAMs
with common I/O pins. They are manufactured in compliance with the JEDEC-standard 209 pin BGA package pinouts defined
for SigmaRAMs. They integrate input registers, high speed RAM, output registers, and a two-deep write buffer onto a single
monolithic IC. Single Data Rate (SDR) Pipelined (PL) read operations and Late Write (LW) write operations are supported,
providing a high-performance user interface. Positive and negative output clocks are provided for applications requiring sourcesynchronous operation.
All address and control input signals are registered on the rising edge of the CK differential input clock.
During read operations, output data is driven valid once, from the rising edge of CK, one full cycle after the address and control
signals are registered.
During write operations, input data is registered once, on the rising edge of CK, one full cycle after the address and control
signals are registered.
Output drivers are series-terminated, and output impedance is programmable via the ZQ control pin. When an external resistor
RQ is connected between ZQ and VSS, the impedance of the SRAM’s output drivers is set to ~RQ/5.
300 MHz operation (300 Mbps) is obtained from a single 1.8V power supply. JTAG boundary scan interface is provided using
a subset of IEEE standard 1149.1 protocol.

(A1 xor A0), A0
Up to three (3) Continue operations may be initiated after a Read or Write operation is initiated to burst transfer up to four
(4) distinct pieces of data per single external address input. If a fourth (4th) Continue operation is initiated, the internal address wraps back to the initial external (base) address.
•Depth Expansion
Depth expansion in these devices is supported via programmable chip enables E2 and E3. The active levels of E2 and E3 are
programmable through the static inputs EP2 and EP3 respectively. When EP2 is tied “high”, E2 functions as an active-high
input. When EP2 is tied “low”, E2 functions as an active-low input. Similarly, when EP3 is tied “high”, E3 functions as an
active-high input. And, when EP3 is tied “low”, E3 functions as an active-low input.
The programmability of E2 and E3 allows four banks of depth expansion to be accomplished with no additional logic. By
programming E2 and E3 of four devices in a binary sequence (00, 01, 10, 11), and by driving E2 and E3 with external address
signals, the four devices can be made to look like one larger device.
When these devices are deselected via chip enable E1, the output clocks continue to toggle. However, when these devices
are deselected via programmable chip enables E2 or E3, the output clocks are forced to a Hi-Z state. See the Clock Truth
Table for further information.
•Output Driver Impedance Control
The impedance of the data and clock output drivers in these devices can be controlled via the static input ZQ. When an external impedance matching resistor (RQ) is connected between ZQ and VSS, output driver impedance is set to one-fifth the
value of the resistor, nominally. See the DC Electrical Characteristics section for further information.
Output driver impedance is updated whenever the data output drivers are in an inactive (High-Z) state. See the Clock Truth
Table section for information concerning which commands deactivate the data output drivers.
At power up, 8192 clock cycles followed by any command that deactivates the data output drivers are required to ensure that
the output impedance has reached the desired value.
Note: The impedance of the output drivers will drift somewhat due to changes in temperature and voltage. Consequently,
during operation, the output drivers should be deactivated periodically in order to update the output impedance and ensure
that it remains within specified tolerances.
•Power-Up Sequence
For reliability purposes, Sony recommends that power supplies power up in the following sequence: VSS, VDD, VDDQ, VREF,
and Inputs. VDDQ should never exceed VDD. If this power supply sequence cannot be met, a large bypass diode may be required between VDD and VDDQ. Please contact Sony Memory Application Department for further information.

•Test Mode Description
These devices provide a JTAG Test Access Port (TAP) and Boundary Scan interface using a limited set of IEEE std. 1149.1
functions. This test mode is intended to provide a mechanism for testing the interconnect between master (processor, controller, etc.), SRAMs, other components, and the printed circuit board.
In conformance with a subset of IEEE std. 1149.1, these devices contain a TAP Controller and four TAP Registers. The TAP
Registers consist of one Instruction Register and three Data Registers (ID, Bypass, and Boundary Scan Registers).
The TAP consists of the following four signals:
TCK:
TMS:
TDI:
TDO:
Test Clock
Test Mode Select
Test Data In
Test Data Out
Induces (clocks) TAP Controller state transitions.
Inputs commands to the TAP Controller. Sampled on the rising edge of TCK.
Inputs data serially to the TAP Registers. Sampled on the rising edge of TCK.
Outputs data serially from the TAP Registers. Driven from the falling edge of TCK.
Disabling the TAP
When JTAG is not used, TCK should be tied “low” to prevent clocking the SRAM. TMS and TDI should either be tied “high”
through a pull-up resistor or left unconnected. TDO should be left unconnected.
Note: Operation of the TAP does not disrupt normal SRAM operation except when the EXTEST-A or SAMPLE-Z instruction is selected. Consequently, TCK, TMS, and TDI can be controlled any number of ways without adversely affecting the
functionality of the device.

TAP Controller
The TAP Controller is a 16-state state machine that controls access to the various TAP Registers and executes the operations
associated with each TAP Instruction (see Figure 7 below). State transitions are controlled by TMS and occur on the rising
edge of TCK.
The TAP Controller enters the “Test-Logic Reset” state in one of two ways:
1. At power up.
2. When a logic “1” is applied to TMS for at least 5 consecutive rising edges of TCK.
The TDI input receiver is sampled only when the TAP Controller is in either the “Shift-IR” state or the “Shift-DR” state.
The TDO output driver is active only when the TAP Controller is in either the “Shift-IR” state or the “Shift-DR” state.

Preliminary
TAP Registers
TAP Registers are serial shift registers that capture serial input data (from TDI) on the rising edge of TCK, and drive serial
output data (to TDO) on the subsequent falling edge of TCK. They are divided into two groups: “Instruction Registers” (IR),
which are manipulated via the “IR” states in the TAP Controller, and “Data Registers” (DR), which are manipulated via the
“DR” states in the TAP Controller.
Instruction Register (IR - 3 bits)
The Instruction Register stores the various TAP Instructions supported by these devices. It is loaded with the IDCODE instruction at power-up, and when the TAP Controller is in the “Test-Logic Reset” and “Capture-IR” states. It is inserted between TDI and TDO when the TAP Controller is in the “Shift-IR” state, at which time it can be loaded with a new instruction.
However, newly loaded instructions are not executed until the TAP Controller has reached the “Update-IR” state.
The Instruction Register is 3 bits wide, and is encoded as follows:
Code
(2:0)
Instruction
Description
000
EXTEST-A
Loads the individual logic states of all signals composing the SRAM’s I/O ring into the
Boundary Scan Register when the TAP Controller is in the “Capture-DR” state, and inserts the
B-Scan Register between TDI and TDO when the TAP Controller is in the “Shift-DR” state.
Also enables the SRAM’s data and clock output drivers, and moves the contents of the B-Scan
Register associated with the data and clock output signals to the input side of the SRAM’s output register. The SRAM’s input clock can then be used to transfer the B-Scan Register contents
directly to the data and clock output pins (the input clock controls the SRAM’s output register). Note that newly captured and/or shifted B-Scan Register contents do not appear at the

See the Boundary Scan Register description for more information.

IDCODE
Loads a predefined device- and manufacturer-specific identification code into the ID Register
when the TAP Controller is in the “Capture-DR” state, and inserts the ID Register between
TDI and TDO when the TAP Controller is in the “Shift-DR” state.
See the ID Register description for more information.

SAMPLE-Z
Loads the individual logic states of all signals composing the SRAM’s I/O ring into the
Boundary Scan Register when the TAP Controller is in the “Capture-DR” state, and inserts the
B-Scan Register between TDI and TDO when the TAP Controller is in the “Shift-DR” state.
Also disables the SRAM’s data and clock output drivers.

Bypass Register (DR - 1 bit)
The Bypass Register is one bit wide, and provides the minimum length serial path between TDI and TDO. It is loaded with
a logic “0” when the BYPASS instruction has been loaded in the Instruction Register and the TAP Controller is in the “Capture-DR” state. It is inserted between TDI and TDO when the BYPASS instruction has been loaded into the Instruction Register and the TAP Controller is in the “Shift-DR” state.
ID Register (DR - 32 bits)
The ID Register is loaded with a predetermined device- and manufacturer-specific identification code when the IDCODE
instruction has been loaded into the Instruction Register and the TAP Controller is in the “Capture-DR” state. It is inserted
between TDI and TDO when the IDCODE instruction has been loaded into the Instruction Register and the TAP Controller
is in the “Shift-DR” state.
The ID Register is 32 bits wide, and is encoded as follows:

Bit 0 is the LSB of the ID Register, and Bit 31 is the MSB. When the ID Register is selected, TDI serially shifts data into the
MSB, and the LSB serially shifts data out through TDO.
Boundary Scan Register (DR - 123 bits for x72, 84 bits for x36, 65 bits for x18)
The Boundary Scan Register is equal in length to the number of active signal connections to the SRAM (excluding the TAP
pins) plus a number of place holder locations reserved for functional and/or density upgrades. It is loaded with the individual
logic states of all signals composing the SRAM’s I/O ring when the EXTEST-A, SAMPLE, or SAMPLE-Z instruction has
been loaded into the Instruction Register and the TAP Controller is in the “Capture-DR” state. It is inserted between TDI and
TDO when the EXTEST-A, SAMPLE, or SAMPLE-Z instruction has been loaded into the Instruction Register and the TAP
Controller is in the “Shift-DR” state.
The Boundary Scan Register contains the following bits:

Note: CK and CK are connected to a differential input receiver that generates a single-ended input clock to these devices.
Therefore, in order to capture deterministic values for these signals in the Boundary Scan Register, they must be at opposite
logic levels when sampled.
Note: When an external resistor RQ is connected between the ZQ pin and VSS, the value of the ZQ signal captured in the
Boundary Scan Register is non-deterministic.

Boundary Scan Register Bit Order Assignments
The tables below depict the order in which the bits are arranged in the Boundary Scan Register. Bit 1 is the LSB and bit 123
(for x72) or bit 84 (for x36) or bit 65 (for x18) is the MSB. When the Boundary Scan Register is selected, TDI serially shifts
data into the MSB, and the LSB serially shifts data out through TDO.
