PrechargeAll command

(RAS#=”L”,CAS#=”H”,WE#=”L”,BS =Don t care,A10 =”H”,A0-A9 =Don ’t care)

The PrechargeAll command precharges all the four banks simultaneously and can be issued even if all banks are

not in the active state.All banks are then switched to the idle state.

4

Read command

(RAS#=”H”,CAS#=”L”,WE#=”H”,BS =Bank,A10 =”L”,A0-A7 =Column Address)

The Read command is used to read a burst of data on consecutive clock cycles from an active row in an active

bank.The bank must be active for at least tRCD(min.)before the Read command is

issued.During read

bursts,the valid data-out element from the starting column address will be available following the CAS#latency

after the issue of the Read command.Each subsequent data- out element will be valid by the next positive clock

edge (refer to the following figure).The DQs go into high-impedance at the end of the burst unless other com-

mand is initiated.The burst length,burst sequence,and CAS#latency are determined by the mode register which

is already programmed.A full-page burst will continue until terminated (at the end of the page it will wrap to

column 0 and continue).
