4Mb Ultra-Low Power Asynchronous CMOS SRAM w/ Dual
Vcc and VccQ for Ultimate Power Reduction
256K×16 bit POWER SAVER TECHNOLOGY
Overview
Features
The N04Q16yyC2B are ultra-low power memory
devices 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 ultra-low active and standby 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. The 4Mb SRAM 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
active operating power and the dual power supply
rails allow very low voltage operation while
maintaining 3V I/O capability. The device can
operate over a very wide temperature range of 0oC
to +70oC for the lowest power and is also available
in the industrial range of -40oC to +85oC. The
devices are available in standard BGA and TSOP
packages. The devices are also available as
Known Good Die (KGD) for embedded package
applications.

1. When UB and LB are in select mode (low), I/O0 - I/O15 are affected as shown. When LB only is in the select mode only I/O0 - I/O7
are affected as shown. When UB is in the select mode only I/O8 - I/O15 are affected as shown.
2. When the device is in standby mode, control inputs (WE, OE, UB, and LB), address inputs and data input/outputs are internally
isolated from any external influence and disabled from exerting any influence externally.
3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.
