DESCRIPTION:
ISSI's IS42SM/RM32160C is a 512Mb Mobile Syn-
chronous 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 signals are registered on the rising edge of the
clock input, CLK. The 512Mb SDRAM is internally con-
figured by stacking two 256Mb, 16Mx16 devices. Each
of the 4M x32 banks is organized as 8192 rows by 512
columns by 32 bits.
