The IS43TR16640A-15GBLI is a 1Gb DDR3 SDRAM supports 1333MT/s data rate. It has high speed data transfer rates with system frequency up to 933MHz, 8 internal banks for concurrent operation and 8-bit pre-fetch architecture. CK and CK# are differential clock inputs. All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK#. CKE HIGH activates and CKE Low deactivates, internal clock signals and device input buffers and output drivers. All commands are masked when CS# is registered HIGH. CS# provides for external Rank selection on systems with multiple Ranks. CS# is considered part of the command code. On Die Termination: ODT (registered HIGH) enables termination resistance internal to the DDR3 SDRAM. When enabled, ODT is only applied to each DQ, DQSU, DQSU#, DQSL, DQSL#, DMU and DML signal. The ODT pin will be ignored if MR1 and MR2 are programmed to disable RTT.
