General Description
The M1T1HT18PL32E is a 1Mbit (1,084,576 bits), high speed, embedded 1T-SRAM macro. The
M1T1HT18PL32E is organized as 32K(32,768) words of 32 bits. The mac ro employs a pipelined read timing
interface with late write timing. W rite contr ol over individual bytes in the input data is achieved through the use
of the byte write enable (bweb) input signals. T he M1T1HT18PL32E m acro is implem ented using MoSys 1T SRAM technology, resulting in extremely high density and performance.
