16Mb (x16) SDRAM PART NUMBER
MT48LC1M16A1TG S 1 Meg x 16
GENERAL DESCRIPTION
The 16Mb SDRAM is a high-speed CMOS, dynamic
random-access memory containing 16,777,216 bits. It is
internally configured as a dual 512K x 16 DRAM with a
synchronous interface (all signals are registered on the
positive edge of the clock signal, CLK). Each of the 512K x
16-bit banks is organized as 2,048 rows by 256 columns by
16 bits. Read and write accesses to the SDRAM are burst
oriented; accesses start at a selected location and continue
for a programmed number of locations in a programmed
