Features

◆

32K x 32 memory configuration

The IDT71V433 SRAM contains write, data-input, address and

controlregisters.Therearenoregisters inthedataoutputpath(flow-

througharchitecture). Internallogicallows the SRAMtogenerate a

self-timed write based upon a decision which can be left until the

extreme end of the write cycle.

The burstmode feature offers the highestlevelofperformance to

the arrayaftera clock-to-data access time delayfromthe risingclock

the subsequent three cycles of output data will be available to the

user on the next three rising clock edges. The order of these three

addresses willbe definedbythe internalburstcounterandthe LBO

— 12 12ns Clock-to-DataAccess (50MHz)

LBO input selects interleaved or linear burst mode
