DESCRIPTION
1.
2.
The M5M4V16169DTP/RT is a 16M-bit Cached DRAM which integrates input
registers, a 1,048,576-word by 16-bit dynamic memory array and a 1024- word
by 16-bit static RAM array as a Cache memory (block size 8x16) onto a single
monolithic circuit. The block data transfer between the DRAM and the data
transfer buffers (RB1/RB2/WB1/WB2) is performed in one instruction cycle, a
fundamental advantage over a conventional DRAM/SRAM cache.
The RAM is fabricated with a high performance CMOS process, and is ideal for
large-capacity memory systems where high speed, low power dissipation, and
low cost are essential. The use of quadruple-layer polysilicon process combined
with silicide and double layer aluminum wiring technology, a single-transistor
dynamic storage stacked capacitor cell, and a six-transistor static storage cache
cell provide high circuit density at reduced costs.

NOTES
1) For the DPD function, the RAS#, CAS# and DTD# inputs are
DON'T CARE except for the L,L,H combination. (Respectively).
2) The unused addresses must be set to Low.
3) Use New: If BW or BWT or BWTW is initiated the same cycle
as DWT1 or DWT1R, new data is loaded into the buffer
and transferred to DRAM.
4) Clear 1 or 2 Transfer Mask Bits (as addressed by As0-2 and DQCU/L).
MITSUBISHI ELECTRIC

Command
5) Actual number of bits transfer depends on the state of the DTBW Mask and
the DQCU/DQCL inputs. Note: If DQC(U/L) is Low, the corresponding DQ(s)
is(are) disabled (Input and Output Buffer). SR,SW,BR and BW cycles
with DQCU and DQCL Low result in a Deselect SRAM operation.
6) Following a DWT1 or DWT1R cycle, the entire WB1 Transfer Mask is Set .
(i.e. , data can no longer be transferred from WB1 to DRAM.)
Succeeding Buffer-Writes or Buffer Write Transfers will Clear Mask bits.
7) CMd# during current cycle must be High (see timing diagram for Auto-Refresh).
8) CMd# during current cycle must be Low (see timing diagram for Self-Refresh).

Input
Master Clock Provides the fundamental timing and the internal clock frequency for
the CDRAM. All external timing parameters (with the exception of G# in read cycle
and CMd# in Self refresh cycle) are specified with respect to the rising edge of K.
Input
DRAM Clock Mask controls the operation of the internal DRAM master clock (K).
When CMd# is Low at the rising edge of K, the internal DRAM master clock (K) for
the following cycle is ceased and input stages are powered-off, resulting in a DRAM
Power Down.
Input
Row Address Strobe is used in conjunction with Master clock K (depending on the
states of CMd#, CAS#, and DTD#) to activate the DRAM (latching the Row Address
lines and accessing 1 of 4096 rows), initiate a DRAM precharge cycle, perform a
DRAM Read or Write Transfer, DRAM Write Transfer & Read, set the command
registers, start an Auto-Refresh cycle, enter a Self-Refresh cycle,create a DRAM
NOP cycle, or power down the DRAM.
Input
Column Address Strobe is used in conjunction with the Master Clock K to latch the
Column addresses. When preceded by RAS# in a DRAM access cycle, CAS#
initiates a DRAM Write Transfer (WB1/2 -> DRAM, if DTD#=L), DRAM Write
Transfer & Read (WB1/2 -> DRAM -> RB, if DTD#=L) or DRAM Read Transfer
(DRAM -> RB, if DTD#=H), depending on the state of DTD# (see DTD# pin
description).
Input
Data Transfer Direction controls DRAM-to-RB(read) / WB-to-DRAM (write)
direction. If preceded by a RAS# low cycle, both CAS# and DTD# low (on the
rising edge of K) initiate a DRAM Write Transfer cycle. If DTD# stays High with the
above conditions, a DRAM Read Transfer cycle results. DTD# can also initiate
DRAM Activate, DRAM Precharge, Auto-Refresh, Set-Command Register, and
Self Refresh cycles.
Input
DRAM Address Lines are Multiplexed to reduce pin count. Ad0-Ad11 (@
RAS=low,CAS=high,DTD=high, K=Rising edge) specify the Row Address of the
DRAM to activate and refresh the selected page and Ad3-Ad7 (@
RAS=high,CAS=low,K=Rising edge) specify the Block Address of the DRAM. In
addition, Ad0-Ad2 (@ RAS=high,CAS=low, K=Rising edge) specify the transfer
operation of the DRAM . Also Ad0-Ad9 (@RAS=low,CAS=low, DTD=low,
K=Rising Edge) are used as the command in set command register cycle.
Input
The Chip Select controls the operation of the CDRAM. When CS#=H at the rising
edge of K and the previous CMd# or CMs# is high, the chip is in No Operation
mode.
Input
SRAM Clock Mask controls the operation of the internal SRAM master clock (Ks).
When CMs# is asserted at a rising edge of K, the internal SRAM master clock for
the following cycle is suspended, resulting in the power down of the SRAM portion
of the circuit, including the Sense Amps. CMs# can also be used to retain output
data during SRAM power-down.

PIN DESCRIPTIONS(2)
Input
DQCu/l are I/OByte control signals. If G#=Low, DQCu/l have a control of output
impedence: DQCu controls upper DQs (DQ8-15) & DQCl controls lower DQs (DQ0-7).
DQCu/l also control both input data during SRAM Writes or Buffer Writes and transfer
mask during Buffer Writes. (WB1 transfer Masks for each byte are written (bits are
cleared) during Buffer Writes depending on DQCu/l inputs.)
WE#
Input
Write Enable controls SRAM and Buffer read and write operations. A high on the WE#
pin causes either a Buffer Read, SRAM Read, Buffer Read Transfer and/or a Buffer
Read Transfer & Read to occur (depending on the state of the CC0# and CC1# bits).
A low on the WE# pin causes either a Buffer Write, SRAM Write, Buffer Write Transfer
and/or a Buffer Write Transfer & Write to occur (depending on the state of the CC0#
and CC1# inputs)
CC0#,CC1#
Inputs
The Control Clock Inputs control SRAM and Buffer operations. CC0# is Low for all
Buffer Writes, Reads, and Transfers, and High for all other SRAM operations. CC1# is
high for all Buffer Read Transfers and Buffer Write Transfers , and Deselect SRAM.
As0-As9
Inputs
SRAM Addresses are non-multiplexed, and access 1024 - 16-bit words ( configured as
128 Rows X 8 Columns X 16 Bits, where the Block Size is 8 X 16) in the SRAM array.
As0-As3 select word address within a block, and As3-As9 select the SRAM row(block).
G#
Input
The Output Enable is an asynchronous input. G#=high forces the outputs to high
impedence.
DQ0-DQ15
Inputs /
Outputs
DQCl,DQCu
VccQ
Supply
Output operation is either transparent, latched, or registered depending on the state of
the command register. The Data Lines for the CDRAM are asynchronously controlled
by G#.
VccQ is the DQ power supply and allows the device to operate in a mixed voltage
system (e.g., 5V data bus). As specified in the Table: Recommended Operating
Conditions, VccQ must be greater-than or equal-to the highest voltage experienced
by the data bus. For 3.3V system operation, VccQ may be tied to Vcc.

MODE DESCRIPTIONS (1)
No Operation. Outputs are high-impedance. All input buffers remain active.
NOP
SRAM
Power-Down
If CMs#=Low at the rising edge of K, the SRAM enters SRAM Power Down at the next rising
edge of K. During this mode, the internal SRAM K clock becomes inactive. The Output
Buffers remain enabled and are controlled by G#. All input buffers of SRAM clocks and
SRAM addresses are inactive.
Deselect SRAM
All transfer functions and input/output operations to and from the SRAM and Buffer are
disabled. This cycle is useful for output impedance control (Hi-Z,Low-Z) without G#. Output
buffers are active during this cycle for registered output mode control.
SRAM Read
Data is read from the SRAM to the I/O pins. Addresses As0-As9 are used to select the data
to be read. As3-As9 decode the SRAM Row (=Block), and As0-As2 decode (1 of 8) the 16bit word. DQCu and DQCl control the impedence (High-Z/Low-Z) of the upper and lower
bytes, respectively.
Data is written from the I/O pins to the SRAM. Addresses As0-As9 are used to select the
location to be written. As3-As9 decode the SRAM Row (=Block), and As0-As2 decode
(1of8) the 16-bit word to be written. DQCUu and DQCl control Upper and Lower byte writes,
respectively.

Power-Down
If CMd#=Low at the rising edge of K, the DRAM enters DRAM Power Down at the next rising
edge of K. During this mode, the internal DRAM K clock becomes inactive. Also all input
buffers of DRAM clocks and DRAM addresses are inactive. Note that the latency of DRAM
Read Transfer cycle is not counted up in this cycle.
DRAM NOP
The DNOP cycle is used when no other DRAM operations are desired, holding the DRAM in
its present (precharge/activate) state.
A Block (8x16) is transferred from the DRAM to the Read Buffer1 and 2 (RB1,RB2) as specified
by Addresses Ad3-Ad7. Addresses Ad8-Ad11 and Ad0-Ad2 must be set to Low. After the
Latency Period (specified in the Access Latency Table) new data will be present in the Read
Buffer2. Prior to the Latency timeout, old data will be present in the RB2. (Notes 1,2,4)

Internally, the active DRAM Row is deselected (completing the refresh process) and page-mode is
disabled. The DRAM is precharged prior to another DRAM Activate cycle.
DRAM
Auto-Refresh
Internally, a DRAM row is selected and refreshed (as addressed by an internal, self-incrementing
counter), followed by an internally generated Precharge cycle. The Auto refresh cycle can be
implemented only if the DRAM is in Precharge state (i.e., a Precharge or Auto-Refresh cycle
occurred more recently than an Acitvate cycle). DRAM Auto-Refresh is similar to a CAS-BeforeRAS (CBR) mode in standard DRAMs.
DRAM
Self Refresh
All clock buffers are suspended, and CMd# asynchronously controls Self Refresh (CMd# rising
edge initiates exit from Self Refresh). During Self Refresh, device enters a low power mode, with
2048 automatic refresh cycles.
Set
Command
Register
When SCR is initiated,the addresses present on the Ad0-Ad11 DRAM Address pins determine the
DRAM Read Transfer Latency, the Output Mode (transparent / latched / registered), and WB1
transfer mask mode (set-all/ no change). No DRAM operation is executed in this cycle. Refer to
the SCR Truth Table for legal Address values.
During SCR cycle and the following 3 clock cycles(totally 4 clock cycles), only NOP,DNOP orDPD
are allowed in DRAM portion and only NOP,DES or SPD are done in SRAM portion. The set
commands are valid at least after the above 4 clocks later and the previous function is not
guaranteed to work if it has not been completed.(i.e. DRT ,DWT1&R,DWT2&R and SR,BR and
BRTR with registered output mode.)
Notes:
1) This function is performed in a Latency period specified in the Access Latency Table.
2) After the Latency Period (specified in the Access Latency Table) new data will be present
in the Read Buffer2. Prior to the Latency timeout, old data will be present in the RB2.
3) After data has been transferred from WB1, the entire WB1 Mask is Set.
4) Valid Ad0-Ad2 addresses are shown in the FUNCTION TRUTH TABLE.
Power-On sequence
Before starting normal operation, the following power on sequence is necessary.
1) Apply power and maintain stable power (pause) for 500us.
2) Perform a precharge (PCG) operation.
3) After tRP, perform 8 auto refresh commands (ARF) with adequate interval (tRC).
4) Issue set command register (SCR) to initilize the mode register.
After this sequence, the RAM is in idle state and ready for normal operation.
Note that DNOP / DPD and DES / SPD or NOP command will be the stand-by command
for the above power sequence.
Vcc must be powered-on at the same time or before VccQ is on.
And Vcc must be powered-off at the same time or after VccQ is off.

* Latency is the number of clock
cycles required to transfer new
data from the DRAM to the Read
Buffer . Therefore, it can be
adjusted to the clock frequency of
the system.
