MT48LC4M16A2TG Synchronous Dram MICRON Original Package TSOP Tray
MT48LC16M4A2 – 4 Meg x 4 x 4 banks
GENERAL DESCRIPTION
The Micron® 64Mb SDRAM is a high-speed CMOS,
dynamic random-access memory containing 67,108,864 bits.
It is internally configured as a quadbank DRAM with a synchronous
interface
(all signals are registered on the positive edge of the clock
signal, CLK).
Each of the x4’s 16,777,216-bit banks is organized as 4,096 rows by
1,024 columns by 4 bits.
Each of the x8’s 16,777,216-bit banks is organized as 4,096 rows by
512 columns by 8 bits.
Each of the x16’s 16,777,216- bit banks is organized as 4,096 rows
by 256 columns by 16 bits.
