DESCRIPTION
The
ISSI IS61LPD/VPD51236A and IS61LPD/VP-
D102418A are high-speed, low-power synchronous
staticRAMs designed to provide burstable, high-performance
memory for communication and networking applications.
TheIS61LPD/VPD51236Aisorganizedas524,288words
by36bits,andtheIS61LPD/VPD102418Aisorganized
as 1,048,576 words by 18 bits. Fabricated with
ISSI's
advanced CMOS technology, the device integrates a
2-bit burst counter, high-speed SRAM core, and high-
drive capability outputs into a single monolithic circuit. All
synchronous inputs pass through registers controlled by
apositive-edge-triggeredsingleclockinput.
Writecyclesareinternallyself-timedandareinitiatedbythe
risingedgeoftheclockinput.Writecyclescanbeoneto
four bytes wide as controlled by the write control inputs.
Separate byte enables allow individual bytes to be written.
Thebytewriteoperationisperformedbyusingthebytewrite
enable (BWE) input combined with one or more individual
byte write signals (BWx). Inaddition,GlobalWrite(GW)
is available for writing all bytes at one time, regardless of
the byte write controls.

input pins. Subsequent burst addresses can be gener-
ated internally and controlled by the ADV (burst address
advance) input pin.
