Features
M13S256328A
2M x 32 Bit x 4 Banks
Double Data Rate SDRAM
z JEDEC Standard
z Internal pipelined double-data-rate architecture, two data access per clock cycle
z Bi-directional data strobe (DQS)
z On-chip DLL
z Differential clock inputs (CLK and CLK )
z DLL aligns DQ and DQS transition with CLK transition
z Quad bank operation
z CAS Latency : 2; 2.5; 3
z Burst Type : Sequential and Interleave
z Burst Length : 2, 4, 8, full page
z Full page burst length for sequential burst type only
z Start address of the full page burst should be even
z All inputs except data & DM are sampled at the rising edge of the system clock(CLK)
z Data I/O transitions on both edges of data strobe (DQS)
z DQS is edge-aligned with data for reads; center-aligned with data for WRITE
z Data mask (DM) for write masking only
z V_DD = 2.3V ~ 2.7V, V_DDQ = 2.3V ~ 2.7V
z Auto & Self refresh
z 64ms refresh period (8K cycle)
z SSTL-2 I/O interface
z 144Ball FBGA package
