GENERAL DESCRIPTION

The MT4C4001J is a randomly accessed solid-state memory containing 4,194,304 bits organized in a x4 configuration. During READ or WRITE cycles each bit is uniquely addressed through the 20 address bits which are entered 10 bits (A0-A9) at a time. RAS is used to latch the first 10 bits and CAS the later 10 bits. A READ or WRITE cycle is selected with the WE input. A logic HIGH on WEdictates READ mode while a logic LOW on WE dictates WRITE mode. During a WRITE cycle, data-in (D) is latched by the falling edge of WE or CAS, whichever occurs last.

FEATURES
