512Mb Mobile Synchronous DRAM
FEATURES:
DESCRIPTION:
ISSI's IS42VM32160C is a 512Mb Mobile 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
x32ꢀbanksꢀisꢀorganizedꢀasꢀ8192ꢀrowsꢀbyꢀ512ꢀcolumnsꢀ
by 32 bits.
•ꢀ Fully synchronous; all signals referenced to a
positive clock edge
•ꢀ Internal bank for hiding row access and pre-
charge
•ꢀ Programmable CAS latency: 2, 3
•ꢀ Programmable Burst Length: 1, 2, 4, 8, and Full
Page
•ꢀ Programmable Burst Sequence:
•ꢀ Sequential and Interleave
•ꢀ Auto Refresh (CBR)
•ꢀ TCSR (Temperature Compensated Self Refresh)
