Preliminary

DESCRIPTION

The MSM514400E/EL is a 1,048,576-word × 4-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS

technology. The MSM514400E/EL 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

MSM514400E/EL is available in a 26/20-pin plastic SOJ, 26/20-pin plastic TSOP. The MSM514400EL (the

low-power version) is specially designed for lower-power applications.

FEATURES

• 1,048,576-word × 4-bit configuration

• Single 5V power supply, ± 10% tolerance

• Input

: TTL compatible, low input capacitance

• Output : TTL compatible, 3-state

• Refresh : 1024 cycles/16 ms, 1024 cycles/128 ms (L-version)

• Fast page mode, read modify write capability

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

• Multi-bit test mode capability

• Package options:

26/20-pin 300mil plastic SOJ (SOJ26/20-P-300-1.27)

(Product : MSM514400E/EL-xxSJ)

26/20-pin 300mil plastic TSOP (TSOPII26/20-P-300-1.27-K) (Product : MSM514400E/EL-xxTS-K)
