DESCRIPTION
M2V28S20TP is organized as 4-bank x 8,388,608-word x 4-bit Synchronous DRAM with LVTTL
interface and M2V28S30TP is organized as 4-bank x 4,194,304-word x 8-bit and M2V28S40TP 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.
M2V28S20TP,M2V28S30TP,M2V28S40TP achieves very high speed data rates up to 133MHz, and is
suitable for main memory or graphic memory in computer systems.
