DESCRIPTION
The

LPS25636AandIS61LPS/VPS51218Aarehigh-speed,
low-powersynchronousstaticRAMs designed to provide
burstable, high-performance memory for communication
andnetworkingapplications.TheIS61LPS/VPS25636A
and IS64LPS25636Aareorganizedas262,144 words
by36bits.TheIS61LPS25632Aisorganizedas262,144
wordsby32bits.TheIS61LPS/VPS51218Aisorganized
as524,288wordsby18bits.Fabricatedwith
ISSI's ad-
vancedCMOStechnology,thedeviceintegratesa2-bit
burstcounter,high-speedSRAMcore,andhigh-drive
capability outputs into a single monolithic circuit. All
synchronous inputs pass through registers controlled by
apositive-edge-triggeredsingleclockinput.
Writecyclesareinternallyself-timedandareinitiatedby
therisingedgeoftheclockinput.Writecyclescanbe
one to four bytes wide as controlled by the write control
inputs.
Separate byte enables allow individual bytes to be written.
Thebytewriteoperationisperformedbyusingthebyte
write enable (BWE) input combined with one or more
individual byte write signals (BWx). Inaddition,Global
Write(GW) is available for writing all bytes at one time,
regardless of the byte write controls.
