pSRAM Type 3
16 Megabit (1M x 16) CMOS Pseudo SRAM
Features
Description
Pin Description
February 25, 2004 pSRAM_Type03_06A0
pSRAM Type 3 currently includes only a 16M bit device, organized as 1M words
by 16 bits. It is designed with advanced CMOS technology specified RAM featur-
ing low-power static RAM-compatible function and pin configuration. This device
operates from a single power supply. Advanced circuit technology provides both
high speed and low power. It is automatically placed in low-power mode when
CS1# or both UB# and LB# are asserted high or CS2 is asserted low. There are
three control inputs. CS1# and CS2 are used to select the device, and output en-
able (OE#) provides fast memory access. Data byte control pins (LB#,UB#)
provide lower and upper byte access. This device is well suited to various micro-
processor system applications where high speed, low power and battery backup
are required.
