... Easy memory expansion is provided by using an active LOW Chip Select (CE) input and an active LOW Output Enable (OE) input. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IS62C256AL/IS65C256AL is pin compatible with other 32Kx8 SRAMs in plastic SOP or TSOP (Type I) package. 32K X 8 ...
