A3S64D40GTP A3S56D40GTP A3S28D40JTP ZENTEL DDR1 SDRAM
A3S28D40JTP is a 4-bank x 2,097,152-word
x 16bit 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 CLK.
The A3S28D40JTP achieves very high speed clock rate up to 200 MHz .
