M2V64S30BTP-7,-7L,-8,-8L,-8A,-10,-10L (4-BANK x 2097152-WORD x 8-BIT)
M2V64S40BTP-7,-7L,-8,-8L,-8A,-10,-10L (4-BANK x 1048576-WORD x 16-BIT)
DESCRIPTION
The M2V64S20BTP is organized as 4-bank x 4194304-word x 4-bit, M2V64S30BTP is
organized as 4-bank x 2097152-word x 8-bit, and M2V64S40BTP is organized as 4-bank x
1048576-word x 16-bit Synchronous DRAM with LVTTL interface. All inputs and outputs are
referenced to the rising edge of CLK. The M2V64S20BTP, M2V64S30BTP, M2V64S40BTP
achieve very high speed data rate up to 125MHz, and are suitable for main memory or
graphic memory in computer systems.
