WRITE with Auto Precharge
3. Interrupted by a READ (with or without auto precharge):
A READ to bank m will interrupt a WRITE on bank n when
registered, with the data-out appearing
CAS latency
later.
The PRECHARGE to bank n will begin after t
WR
is met,
where t
WR
begins when the READ to bank m is registered.
The last valid
WRITE
to bank n will be data-in registered
one clock prior to the READ to bank m.
4. Interrupted by a WRITE (with or without auto precharge):
A
WRITE
to bank m will interrupt a
WRITE
on bank n when
registered. The PRECHARGE to bank n will begin after
t
WR
is met, where t
WR
begins when the WRITE to bank
m is registered. The last valid data WRITE to bank n will
be data registered one clock prior to a WRITE to bank m.
