DESCRIPTION:
The ISSI's IS42S32160C is a 512Mb Synchronous
DRAM configured as a quad 4M x32 DRAM. It achieves
high-speed data transfer using a pipeline architecture
with a synchronous interface. All inputs and outputs sig-
nals are registered on the rising edge of the clock input,
CLK. The 512Mb SDRAM is internally configured by
stacking two 256MB, 16Mx16 devices. Each of the 4M
x32 banks is organized as 8192 rows by 512 columns
by 32 bits.
