From Command (Bank n)
READ with auto precharge
If A10 is high when a READ command is issued, the READ with auto precharge function
is engaged. The DDR2 SDRAM starts an auto precharge operation on the rising clock
edge that is AL + (BL/2) cycles later than the read with auto precharge command provi-
ded
edge, the start point of the auto precharge operation will be delayed until
satisfied. If
to precharge operation will be delayed until
precharge is pushed out by
happens (not at the next rising clock edge after this event).
When BL = 4, the minimum time from READ with auto precharge to the next ACTIVATE
command is AL + (
auto precharge to the next ACTIVATE command is AL + 2 clocks + (
term (
tion can also be used: AL + BL/2 - 2CK + (
charge does not start earlier than two clocks after the last 4-bit prefetch.
READ with auto precharge command may be applied to one bank while another bank is
operational. This is referred to as concurrent auto precharge operation, as noted in Ta-
ble 42. Examples of READ with precharge and READ with auto precharge with applica-
ble timing requirements are shown in Figure 52 (page 102) and Figure 53 (page 103),
respectively.
