Notes:
Notes:
lowing the PRECHARGE command, a subsequent command to the same bank cannot
be issued until
access of the last data elements.
Examples of READ-to-PRECHARGE for BL = 4 are shown in Figure 48 and in Figure 49
for BL = 8. The delay from READ-to-PRECHARGE period to the same bank is AL + BL/2 -
