The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then rounding off to the next higher integer. 2. Minimum delay is required to complete write. 3. Minimum tRDL=2CLK and tDAL(=tRDL + tRP) is required to complete both of last data wite command(tRDL) and precharge command(tRP). tRDL=1CLK can be supported only in the case under 100MHz with manual precharge mode. 4. All parts allow every cycle column address change. 5. In case of row precharge interrupt, auto precharge and read burst stop.

Parameters depend on programmed CAS latency. 2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter. 3. Assumed input rise and fall time (tr & tf) = 1ns. If tr & tf is longer than 1ns, transient time compensation should be considered, i.e., [(tr + tf)/2-1]ns should be added to the parameter. Note : 1.

OP Code : Operand Code A 0 ~ A 11 & BA 0 ~ BA1 : Program keys. (@MRS) 2. MRS can be issued only at all banks precharge state. A new command can be issued after 2 CLK cycles of MRS. 3. Auto refresh functions are the same as CBR refresh of DRAM. The automatical precharge without row precharge command is meant by "Auto". Auto/self refresh can be issued only at all banks precharge state. 4. BA0 ~ BA1 : Bank select addresses. If both BA 0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected. If BA 0 is "Low" and BA 1 is "High" at read, write, row active and precharge, bank B is selected. If BA 0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank C is selected. If both BA 0 and BA1 are "High" at read, write, row active and precharge, bank D is selected. If A 10 /AP is "High" at row precharge, BA0 and BA 1 is ignored and all banks are selected. 5. During burst read or write with auto precharge, new read/write command can not be issued. Another bank read/write command can be issued after the end of burst. New row active of the associated bank can be issued at tRP after the end of burst. 6. Burst stop command is valid at every burst length. 7. DQM sampled at the positive going edge of CLK masks the data-in at that same CLK in write operation (Write DQM latency is 0), but in read operation it makes the data-out Hi-Z state after 2 CLK cycles. (Read DQM latency is 2). Rev. 1.4 Dec. 2002
