Advance Information
EM512D16
512Kx16 bit Ultra-Low Power Asynchronous Static RAM
Overview
The EM512D16 is an integrated memory device
containing a low power 8 Mbit Static Random
Access Memory organized as 524,288 words by 16
bits. The base design is the same as NanoAmp’s
standard low voltage version, EM512W16. The
device is fabricated using NanoAmp’s advanced
CMOS process and high-speed/ultra low-power/
low-voltage circuit technology. The device pinout is
compatible with other standard 512K x 16 SRAMs.
The device is designed such that a creative user
can improve system power and performance
parameters through use of it’s unique page mode
operation.
