A4S12D30FTP A4S12D40FTP 512M Double Data Rate Synchronous DRAM 512Mb DDR SDRAM Specification A4S12D30FTP A4S12D40FTP Zentel Electronics Corp. Revision 1.2 May, 2011 A4S12D30FTP A4S12D40FTP 512M Double Data Rate Synchronous DRAM DESCRIPTION A4S12D40FTP is a 4-bank x 8,388,608-word x 16-bit, A4S12D30FTP is a 4-bank x 16777216word x 8-bit, 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 512Mb DDR SDRAM achieves very high speed data rate up to 200MHz, and are suitable for main memory in computer systems. FEATURES -Vdd=Vddq=2.5V+0.2V(G6 Grade) -Vdd=Vddq=2.6V+0.1V(G5 Grade) - Double data rate architecture; two data transfers per clock cycle - Bidirectional, data strobe (DQS) is transmitted/received with data - Differential clock inputs (CLK and /CLK) - DLL aligns DQ and DQS trans...
