Simplified Truth Table
4. A10 : Bank select address.
If “Low” at read, (block) write, Row active and precharge, bank A is selected.
If “High” at read, (block) write, Row active and precharge, bank B is selected.
If A9 is “High” at Row precharge, A10 is ignored and both banks are selected.
5. It is determined at Row active cycle.
whether Normal/Block write operates in write per bit mode or not.
For A bank write, at A bank Row active, for B bank write, at B bank Row active.
Terminology : Write per bit = I/O mask
(Block) Write with write per bit mode = Masked (Block ) Write
6. During burst read or write with auto precharge, new read/ (block) write command cannot be issued.
Another bank read/(block) write command can be issued at t
PR
after the end of burst.
7. Burst stop command is valid only t full page burst length.
8. DQM sampled at positive going edge of a CLK masks the data-in at the very CLK (Write DQM latency is 0),
but makes the data-out Hi-Z state after 2 CLK cycles. (Read DQM latency is 2)
9. Graphic features added to SDRAM’s original features.
If DSF is tied to low, graphic functions are disabled and chip operates as a 16M SDRAM with 32 DQ’s.

IF DSF is low, SGRAM functionality is identical to SDRAM functionality.
SGRAM can be used as an unified memory by the appropriate DSF control

SDRAM = Graphic Memory + main Memory
