4Mb Ultra-Low Power Asynchronous CMOS SRAMs
256K × 16 bit POWER SAVER TECHNOLOGY TM
Overview
The N04L1630C2B is an integrated memory
device containing a 4 Mbit Static Random Access
Memory organized as 262,144 words by 16 bits.
The device is designed and fabricated using AMI
Semiconductor’s advanced CMOS technology to
provide both high-speed performance and ultra-low
power. The device operates with two chip enable
(CE1 and CE2) controls and output enable (OE) to
allow for easy memory expansion. Byte controls
(UB and LB) allow the upper and lower bytes to be
accessed independently and can also be used to
deselect the device. The N04L1630C2B is
optimized for the ultimate in low power and is
suited for various applications where ultra-low-
power is critical such as medical applications,
battery backup and power sensitive hand-held
devices. The unique page mode operation saves
operating power while improving the performance
over standard SRAMs. The device can operate
over a very wide temperature range of -40oC to
+85oC and is available in JEDEC standard
packages compatible with other standard 256Kb x
16 SRAMs.
