CONFIGURATION DESCRIPTION
Name System clock Chip select Input Function Active positive going edge sample inputs. Disables enables device operation masking enabling inputs except CLK, DQM. Masks system clock freeze operation from next clock cycle. should enabled least cycle prior command. Disable input buffers power down standby. should enabled 1CLK+t prior valid command. Row/column addresses multiplexed same pins. address RA11, Column address Selects bank activated during address latch time. Selects bank read/write during column address latch time. Latches addresses positive going edge with Enables access precharge. low. low.

Address Bank select address address strobe Column address strobe Write enable Data input/output mask Data input/output Check
Latches column addresses positive going edge with Enables column access. Enables write operation precharge. Latches data starting from CAS, active. Makes data output Hi-Z, after clock masks output. Blocks data input when active. (Byte masking) Data inputs/outputs multiplexed same pins. Check bits ECC.
