A3S28D40JTP - 128M Double Data Rate Synchronous DRAM

Datasheet Summary

Description

A3S28D40JTP is a 4-bank x 2,097,152-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.

Features

- VDD=VDDQ=2.5V+0.2V (-50) - 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 length -.
