4,194,304-Word ¥ 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM5117405B is a 4,194,304-word ¥ 4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology.
The MSM5117405B achieves high integration, high-speed operation, and low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/double-layer metal CMOS process.
The MSM5117405B is available in a 26/24-pin plastic SOJ or 26/24-pin plastic TSOP.
FEATURES
• 4,194,304-word ¥ 4-bit configuration • Single 5 V power supply, ± 10% tolerance • Input : TTL compatible, low input capacitance • Output : TTL compatible, 3-state • Refresh : 2048 cycles/32 ms • Fast page mode with EDO, read modify write capability • CAS before RAS refresh, hidden refresh, RAS-only refresh capability • Multi-bit test mode capability • Package options: 26/24-pin 300 mil plastic SOJ (SOJ26/24-P-300-1.
