MS82V16520

262,144-Word ¥ 32-Bit ¥ 2-Bank Synchronous Graphics RAM

DESCRIPTION

The MS82V16520 is a synchronous graphics random access memory organized as 256 K words ¥ 32

bits ¥ 2 banks.

This device can operate up to 143 MHz by using synchronous interface. In addition, it has 8-column

Block Write function and Write per bit function which improves performance in graphics

systems.

FEATURES

• 262,144 words ¥ 32 bits ¥ 2 banks memory

• Single 3.3 V ±0.3 V power supply

• LVTTL compatible inputs and outputs

• All input signals are latched at rising edge of system clock

• Auto precharge and controlled precharge

• Internal pipelined operation: column address can be changed every clock cycle

• Dual internal banks controlled by A10 (Bank Address: BA)

• Independent byte operation via DQM0 to DQM3

• 8-column Block Write function

• Persistent write per bit function

• Programmable burst sequence (Sequential/Interleave)

• Programmable burst length (1, 2, 4, 8 and full page)

• Programmable CAS latency (2, 3)

• Burst stop function (full-page burst)

• Power Down operation and Clock Suspend operation

• Auto refresh and self refresh capability

• 2,048 refresh cycles/32 ms

• Package:

100-pin plastic QFP
