2. Same bank:
The consecutive read command from write with auto precharge (the same bank) is illegal.
It is necessary to separate the two commands with a bank active command.
Read command to Precharge command interval (same bank):
When the precharge command is executed for the same bank as the read command that preceded it, the min-
imum interval between the two commands is one clock. However, since the output buffer then becomes
High-Z after the clocks defined by l
HZP
, there is a case of interruption to burst read data output will be inter-
rupted, if the precharge command is input during burst read. To read all data by burst read, the clocks defined
by l
EP
must be assured as an interval from the final data output to precharge command execution.
READ to PRECHARGE Command Interval (same bank): To output all data
CE Latency = 3, Burst Length = 4
CE Latency = 4, Burst Length = 4
READ to PRECHARGE Command Interval (same bank): To stop output data
CE Latency = 3, Burst Length = 1, 2, 4, 8, full page burst
