IS42SM32160C IS42RM32160C 16Mx32 NOVEMBER2010 512MbMobile SynchronousDRAM FEATURES: DESCRIPTION: ISSI s IS42SM/RM32160C is a 512Mb Mobile Syn- Fully synchronous all signals referenced to a chronous DRAM configured as a quad 4M x32 DRAM. positive clock edge It achieves high-speed data transfer using a pipeline Internal bank for hiding row access and pre- architecture with a synchronous interface. All inputs and charge outputs signals are registered on the rising edge of the Programmable CAS latency: 2, 3 clock input, CLK. The 512Mb SDRAM is internally con- Programmable Burst Length: 1, 2, 4, 8, and Full figured by stacking two 256Mb, 16Mx16 devices. Each Page of the 4M x32 banks is organized as 8192 rows by 512 Programmable Burst Sequence: columns by 32 bits.
