MSM5118165B

1,048,576-Word ´ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO

DESCRIPTION

TheMSM5118165Bisa1,048,576-word´16-bitdynamicRAMfabricatedinOki'ssilicon-gateCMOS technology. The MSM5118165B 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 MSM5118165B is available in a 42-pin plastic SOJ or 50/44-pin plastic TSOP.

FEATURES

•1,048,576-word ´ 16-bit configuration

•Single 5 V power supply, ±10% tolerance

• Input : TTL compatible, low input capacitance

•Output : TTL compatible, 3-state

•Refresh : 1024 cycles/16 ms

•Fast page mode with EDO, read modify write capability

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

•Package options:

42-pin 400 mil plastic SOJ (SOJ42-P-400-1.27) (Product : MSM5118165B-xxJS) 50/44-pin 400 mil plastic TSOP (TSOPII50/44-P-400-0.80-K) (Product : MSM5118165B-xxTS-K)

(TSOPII50/44-P-400-0.80-L) (Product : MSM5118165B-xxTS-L) xx indicates speed rank.
