MT4C4M4A1 Description
The 4 Meg x 4 DRAM is a randomly accessed, solidstate memory containing 16,777,216 bits organized in a x4 configuration. RAS# is used to latch the row address (first 11 bits for 2K and first 12 bits for 4K). Once the page has been opened by RAS#, CAS# is used to latch the column address (the latter 11 bits.
