General Description

A3S56D30ETP is a 4-bank x 8,388,608-word x 8bit, A3S56D40ETP is a 4-bank x 4,194,304-word x 16bit 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 strobe ,and output data and data strobe are referenced on both edges of CLK.

Key Features

  • - Vdd=Vddq=2.5V+0.2V (-5E, -5, -6) - Double data rate architecture ; two data transfers per clock cycle. - Bidirectional , data strobe (DQS) is transmitted/received with data - Differential clock input (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 / 3.0 (programmable) ; Burst.
