524,288x32x2-Bit
CMOS Synchronous Graphic RAM
Operation Mode
Fully synchronous operations are performed to latch the commands at the positive edges of CLK. Table 2
shows the truth table for the operation commands.
Table 2. Truth Table (Note(1), (2))
Note: 1. V = Valid X = Don’t Care L = Low level H = High level
2. CKEn signal is input level when commands are provided.
CKEn-1 signal is input level one clock cycle before the commands are provided.
3. These are states of bank designated by BS signal.
4. Device state is 1, 2, 4, 8, and full page burst operation.
5. The Special Mode Register Set is also available in Row Active State.
6. Power Down Mode can not entry in the burst operation.
When this command assert in the burst cycle, device state is clock suspend mode.
