TRUTH TABLE 4 – Current State Bank n - Command to Bank m
(Notes: 1-6; notes appear below and on next page)
NOTE:
1. This table applies when CKEn-1 was HIGH and CKEn is HIGH (see Truth Table 2) and after
tXSR has been met
(if the previous state was self refresh).
2. This table describes alternate bank operation, except where noted, i.e., the current state is for bank n and the
commands shown are those allowed to be issued to bank m (assuming that bank m is in such a state that the given
command is allowable). Exceptions are covered in the notes below.
3. Current state definitions:
Idle: The bank has been precharged, and tRP has been met.
Row Active: A row in the bank has been activated, and tRCD has been met. No data
bursts/accesses and no register accesses are in progress.
Read: A READ burst has been initiated, with AUTO PRECHARGE disabled, and
has not yet terminated or been terminated.
Write: A WRITE burst has been initiated, with AUTO PRECHARGE disabled, and
has not yet terminated or been terminated.
