Description

The V62C1804096 is a very low power CMOS
static RAM organized as 524,288 words by 8 bits.
Easy memory expansion is provided by an active
LOW CE1

, and active HIGH C E2, an activ e LOW
OE, and t hree static I/O’s. This device has an
automatic power-down mode feature when
deselected.

Address Inputs

These 19 address inputs select one of the 512K x 8
bit segments in the RAM.

CE

,CE2Chip Enable Inputs

CE

1

is active LOW and CE2is active HIGH. Both
chip enables must be active to read from or write to
the device. If either chip enable is not active, the
device is deselected and is in a standby power
mode. The I/O pins will be in the high-impedance
state when deselected.

OE

Output Enable Input

The Output Enable input is active LOW. With chip
enabled, when OE

is LOW and WE HIGH, data of
the selected memory location will be available on
the I/O pins. When OE

is HIGH, the I/O pins will be

in the high impedance state.

WE

WriteEnable Input

The write enable input is active LOW and control s
read and write operations. With the chip enabled,
when WE

is HIGH and OE is LOW, output data will

be present at the I/O pins; when WE

is LOW and

OE

is HI GH, the data presenton the I/ O pins will be

written into the sele cted memo ry locations.
