Activating a Specific Row in a Specific Bank
Upon exiting the self refresh mode, AUTO REFRESH commands must be issued every
15.625µs or less, as both SELF REFRESH and AUTO REFRESH utilize the row refresh
counter.
Before any READ or WRITE commands can be issued to a bank within the SDRAM, a row
in that bank must be “opened.” This is accomplished via the ACTIVE command, which
selects both the bank and the row to be activated (see Figure 8).
After opening a row (issuing an ACTIVE command), a READ or WRITE command may be
issued to that row, subject to the
the clock period and rounded up to the next whole number to determine the earliest
clock edge after the ACTIVE command on which a READ or WRITE command can be
entered. For example, a
results in 2.5 clocks, rounded to 3. This is reflected in Figure 9 on page 21, which covers
any case where 2 <
specification limits from time units to clock cycles).
A subsequent ACTIVE command to a different row in the same bank can only be issued
after the previous active row has been “closed” (precharged). The minimum time
interval between successive ACTIVE commands to the same bank is defined by
A subsequent ACTIVE command to another bank can be issued while the first bank is
being accessed, which results in a reduction of total row-access overhead. The
minimum time interval between successive ACTIVE commands to different banks is
defined by
