5 / 51 page  Feb.'00 MITSUBISHI LSIs MITSUBISHI ELECTRIC SDRAM (Rev.3.2) 64M Synchronous DRAM M2V64S20DTP-6,-6L,-7,-7L,-8,-8L (4-BANK x 4,194,304-WORD x 4-BIT) (4-BANK x 2,097,152-WORD x 8-BIT) (4-BANK x 1,048,576-WORD x 16-BIT) M2V64S30DTP-6,-6L,-7,-7L,-8,-8L M2V64S40DTP-6,-6L,-7,-7L,-8,-8L 5 BASIC FUNCTIONS The M 2V64S20, 30 and 40DTP p rovides basic functions, bank (row) activate, burst read and write, bank (row) precharge, and auto and self refresh. Each command is defined by control signals of /RAS, /CAS and /WE at CLK rising edge. In addition to 3 signals, /CS ,CKE and A10 are used as chip select, refresh option, and precharge option, respectively. To know the detailed definition of commands, please see the command truth table. Activate (ACT) [/RAS =L, /CAS =/WE =H] ACT command activates a row in an idle bank indicated by BA. Read (READ) [/RAS =H, /CAS =L, /WE =H] READ command starts burst read from the active bank indicated by BA. First output data appears after /CAS latency. When A10 =H at this command, the bank is deactivated after the burst read (auto- precharge,READA) Write (WRITE) [/RAS =H, /CAS =/WE =L] WRITE command starts burst write to the active bank indicated by BA. Total data length to be written is set by burst length. When A10 =H at this command, the bank is deactivated after the burst write (auto-p recharge, WRITEA). Precharge (PRE) [/RAS =L, /CAS =H, /WE =L] PRE command deactivates the active bank indicated by BA. This command also terminates burst read /write operation. When A10 =H at this command, all banks are deactivated (p recharge all, PREA). Auto-Refresh (REFA) [/RAS =/CAS =L, /WE =CKE =H] REFA command starts auto-refresh cy cle. Refresh address are generated internally. After this command, the banks are precharged automatically. /CS Chip Select : L=select, H=deselect /RAS Command /CAS Command /WE Command CKE Ref resh Option @ref resh command A10 Precharge Option @precharge or read/write command CLK def ine basic commands |
