DESCRIPTION
M2V28S20ATP is organized as 4-bank x 8,388,608-word x 4-bit Synchronous DRAM with LVTTL
interface and M2V28S30ATP is organized as 4-bank x 4,194,304-word x 8-bit and M2V28S40ATP is organized
as 4-bank x 2,097,152-word x 16-bit. All inputs and outputs are referenced to the rising edge of CLK.
M2V28S20ATP,M2V28S30ATP,M2V28S40ATP achieves very high speed data rates up to 133MHz,
and is suitable for main memory or graphic memory in computer systems.
