Unspecified 

A3V56S30ETP

A3V56S40ETP

256M Single Data Rate Synchronous DRAM

General Description

A3V56S30ETP is organized as 4-bank x 8,388,608-word x 8-bit Synchronous DRAM with LVTTL interface and

A3V56S40ETP is organized as 4-bank x 4,194,304-word x 16-bit. All inputs and outputs are referenced to the rising edge of

CLK. A3V56S30ETP and A3V56S40ETP achieve very high speed data rates up to 166MHz, and are suitable for main

memories or graphic memories in computer systems.
