DESCRIPTION
M2S56D20ATP / AKT is a 4-bank x 16777216-word x 4-bit,
M2S56D30ATP / AKT is a 4-bank x 8388608-word x 8-bit,
M2S56D40ATP/ AKT is a 4-bank x 4194304-word x 16-bit,
double data rate synchronous DRAM, with SSTL_2 interface. All control and address signals are
referenced to the rising edge of CLK.Input data is registered on both edges of data strobes, and output
data and data strobe are referenced on both edges of CLK. The M2S56D20/30/40ATP achieve very high
speed data rate up to 133MHz, and are suitable for main memory in computer systems.
FEATURES
- VDD=VDDQ=2.5V+0.2V
- Double data rate architecture; two data transfers per clock cycle
- Bidirectional, data strobe (DQS) is transmitted/received with data
- Differential clock inputs (CLK and /CLK)
- DLL aligns DQ and DQS transitions
- Commands are entered on each positive CLK edge
- Data and data mask are referenced to both edges of DQS
- 4-bank operations are controlled by BA0, BA1 (Bank Address)
- /CAS latency- 2.0/2.5 (programmable)
- Burst length- 2/4/8 (programmable)
- Burst type- sequential / interleave (programmable)
- Auto precharge / All bank precharge is controlled by A10
- 8192 refresh cycles /64ms (4 banks concurrent refresh)
- Auto refresh and Self refresh
- Row address A0-12 / Column address A0-9,11(x4)/ A0-9(x8)/ A0-8(x16)
- SSTL_2 Interface
- Both 66-pin TSOP Package and 64-pin Small TSOP Package
M2S56D*0ATP: 0.8mm lead pitch 66-pin TSOP Package
M2S56D*0AKT: 0.4mm lead pitch 64-pin Small TSOP Package
- JEDEC standard
- Low Power for the Self Refresh Current ICC6 : 2mA (-75AL , -75L , -10L)

BASIC FUNCTIONS
The M2S56D20/30/40A* provides basic functions, bank (row) activate, burst read / write, bank (row)
precharge, and auto / self refresh. Each command is defined by control signals of /RAS, /CAS and /WE at
CLK rising edge. In addition to 3 signals, /CS ,CKE and A10 are used as chip select, refresh option, and
precharge option, respectively. Refer to the command truth table for the detailed definition of commands.

define basic commands
Refresh Option @refresh command
Precharge Option @precharge or read/write command
Activate (ACT) [/RAS =L, /CAS =/WE =H]
ACT command activates one row in an idle bank indicated by BA.
Read (READ) [/RAS =H, /CAS =L, /WE =H]
READ command starts burst read from the active bank indicated by BA. First output data appears after
/CAS latency. When A10 =H in this command, the bank is deactivated after the burst read (auto-
precharge, READA)
Write (WRITE) [/RAS =H, /CAS =/WE =L]
WRITE command starts burst write to the active bank indicated by BA. Total data length to be written
is defined by burst length. When A10 =H in this command, the bank is deactivated after the burst write
(auto-precharge, WRITEA)
Precharge (PRE) [/RAS =L, /CAS =H, /WE =L]
PRE command deactivates the active bank indicated by BA. This command also terminates burst read
/write operation. When A10 =H in this command, all banks are deactivated (precharge all, PREA ).
Auto-Refresh (REFA) [/RAS =/CAS =L, /WE =CKE =H]
REFA command starts auto-refresh cycle. Refresh addresses including bank address are generated
internally. After this command, the banks are precharged automatically.
