DESCRIPTION

The DS2064 is a 65536–bit low power, fully static ran-

dom access memory organized as 8192 words by eight

bits using CMOS technology. The device operates from

a single power supply with a voltage input between 4.5V

and 5.5V. The chip enable inputs (CE1 and CE2) are

used for device selection and can be used in order to

achieve the minimum standby current mode, which fa-

cilitates both battery operate and battery backup appli-

cations. The device provides fast access time of 200 ns

and is most suitable for low power applications where

battery operation or battery backup for nonvolatility are

required. The DS2064 is a JEDEC–standard 8K x 8

SRAM and is pin–compatible with ROM and EPROM of

similar density.
