FEATURES • 1.8V power supply, 1.8V I/O power • Double-data-rate architecture; two data transfers per clock cycle • Bidirectional data strobe(DQS) • Four banks operation • Differential clock inputs(CK and CK) • MRS cycle with address key programs - CAS Latency ( 3 ) - Burst Length ( 2, 4, 8 ) - Burst Type (Sequential & Interleave) - Partial Self Refresh Type ( Full, 1/2, 1/4 array ) - Internal Temperature Compensated Self Refresh - Driver strength ( 1, 1/2, 1/4, 1/8 ) • All inputs except data & DM are sampled at the positive going edge of the system clock(CK). • Data I/O transactions on both edges of data strobe, DM for masking. • Edge aligned data output, center aligned data input. • No DLL; CK to DQS is not synchronized. • LDM/UDM for write masking only. • 7.8us auto refresh duty cycle. • CSP package.
