10 / 81 page  Document: Rev.1 Page 10 VIS Preliminary VG4632321A 524,288x32x2-Bit CMOS Synchronous Graphic RAM Q DSF BankActivate command MR7 MR6 MR5 MR4 MR3 MR1 MR0 MR2 D CK DQ7 DQ6 DQ5 DQ4 DQ3 DQ2 DQ1 DQ0 CELL DRAM 0 = Masked Note: Only lower byte is shown. The operation is identical for other bytes. Write Per Bit (I/O Mask) Block Diagram A write burst without auto precharge function may be interrupted by a subsequent Write/Block Write, BankPrecharge/PrechargeAll, or Read command before the end of burst length. The interrupt comes from Write/Block Write command can occur on any clock cycle following the previous Write command ( refer to the following figure). DQM0 T0 T1 T2 T3 T4 T5 T6 T7 T8 CLK COMMAND NOP WRITE A WRITE B NOP NOP NOP NOP NOP NOP DIN B2 Write Interrupted by a Write (Burst Length = 4, CAS Latency = 1, 2, 3) DIN B3 1 Clk Interval DIN A0 DIN B0 DIN B1 DQ’s The Read command that interrupts a write burst without auto precharge function should be issued one cycle after the clock edge at which the last data-in element is registered. In order to avoid data contention, input data must be removed from the DQs at least one clock cycle before the first read data appears on the outputs (refer to the following figure). Once the Read command is registered, the data inputs will be ignored, and writes will not be executed. 1 = Not Masked |
