262,144-Word ¥ 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE

DESCRIPTION

The MSM51V4256A is a 262,144-word ¥ 4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS

technology. The MSM51V4256A achieves high integration, high-speed operation, and low-power

consumption because Oki manufactures the device in a quadruple-layer polysilicon/single-layer

metal CMOS process. The MSM51V4256A is available in a 20-pin plastic DIP, 26/20-pin plastic SOJ,

or 20-pin plastic ZIP.

FEATURES

• 262,144-word ¥ 4-bit configuration

• Single 3.3 V power supply, 0.3 V tolerance

• Input

: LVTTL compatible, low input capacitance

• Output : LVTTL compatible, 3-state

• Refresh : 512 cycles/8 ms

• Fast page mode, read modify write capability

• CAS before RAS refresh, hidden refresh, RAS-only refresh capability

• Package options:

20-pin 300 mil plastic DIP

(DIP20-P-300-2.54-W1) (Product : MSM51V4256A-xxRS)

26/20-pin 300 mil plastic SOJ (SOJ26/20-P-300-1.27) (Product : MSM51V4256A-xxJS)

20-pin 400 mil plastic ZIP

(ZIP20-P-400-1.27)

(Product : MSM51V4256A-xxZS)

xx indicates speed rank.
