TABLE 1 – BURST DEFINITION
NOTES:
1.
For a burst length of two, A1-Ai select two-data-element block; A0 selects the
starting column within the block.
2.
For a burst length of four, A2-Ai select four-data-element block; A0-1 select the
starting column within the block.
3.
For a burst length of eight, A3-Ai select eight-data-element block; A0-2 select the
starting column within the block.
4.
Whenever a boundary of the block is reached within a given sequence above, the
following access wraps within the block.

HIGH, the corresponding data inputs will be ignored, and a
WRITE will not be executed to that byte/column location.
PRECHARGE
The PRECHARGE command is used to deactivate the
open row in a particular bank or the open row in all banks.
The bank(s) will be available for a subsequent row access
a specified time (tRP) after the PRECHARGE command is
issued. Except in the case of concurrent auto precharge,
where a READ or WRITE command to a different bank is
allowed as long as it does not interrupt the data transfer
in the current bank and does not violate any other timing
parameters. Input A10 determines whether one or all
banks are to be precharged, and in the case where only
one bank is to be precharged, inputs BA0, BA1 select the
bank. Otherwise BA0, BA1 are treated as “Don’t Care.”
Once a bank has been precharged, it is in the idle state and
must be activated prior to any READ or WRITE commands
being issued to that bank. A PRECHARGE command will
be treated as a NOP if there is no open row in that bank
(idle state), or if the previously open row is already in the
process of precharging.
AUTO PRECHARGE
AUTO PRECHARGE is a feature which performs the
same individual-bank PRECHARGE function described
above, but without requiring an explicit command. This is
accomplished by using A10 to enable AUTO PRECHARGE
