IS43R32800B - 256Mb DDR Synchronous DRAM PRELIMINARY INFORMATION
IS43R32800B is a 4-bank x 2,097,152-word x32bit Double Data Rate Synchronous DRAM, with SSTL_2 interface.
All control and address signals are referenced to the rising edge of CLK.
Input data is registered on both edges of data strobe, and output data and data strobe are referenced on both edges of
IS43R32800B Features
* Vdd/Vddq=2.5V+0.2V (-5, -6, -75)
* Double data rate architecture; two data transfers per clock cycle
* Bidirectional, data strobe (DQS) is transmitted/ received with data
* Differential clock input (CLK and /CLK)
* DLL aligns DQ and DQS transitions with
