鈥?Part Number Example: MT4LC4M4E8DJ-6
Note:
The 4 Meg x 4 EDO DRAM base number differentiates the offerings in
two places -
MT4LC4M4E8.
The third field distinguishes the low voltage
offering: LC designates V
CC
= 3.3V and C designates V
CC
= 5V. The fifth field
distinguishes various options: E8 designates a 2K refresh and E9 designates a
4K refresh for EDO DRAMs.

GENERAL DESCRIPTION
The 4 Meg x 4 DRAM is a randomly accessed, solid-state
memory containing 16,777,216 bits organized in a x4 con-
figuration. 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
