P3S56D40ETP Overview
Description
M2S56D20ATP is a 4-bank x 16,777,216-word x 4-bit, M2S56D30ATP is a 4-bank x 8,388,608-word x 8-bit, M2S56D40ATP is a 4-bank x 4,194,304-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.
Key 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 with CLK transitions edges of DQS
- Commands entered on each positive CLK edge
- data and data mask referenced to both edges of DQS
- 4 bank operation controlled by BA0, BA1 (Bank Address)
- /CAS latency- 2.0/2.5 (programmable)
- Burst length- 2/4/8 (programmable)
