7 / 55 page  MH16S72DAMD -6,-7,-8 1207959552-BIT (16777216 - WORD BY 72-BIT)Synchronous DRAM MITSUBISHI LSIs ( / 55 ) MITSUBISHI ELECTRIC 23.Sep.1999 Preliminary Spec. Some contents are subject to change without notice. MIT-DS-0336-0.0 BASIC FUNCTIONS /S 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 CK def ine basic commands The MH16S72DAMD provides basic functions,bank(row)activate,burst read / write, bank(row)precharge,and auto / self refresh. Each command is defined by control signals of /RAS,/CAS and /WE at CK rising edge. In addition to 3 signals,/S,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] Read(READ) [/RAS =H,/CAS =L, /WE =H] Write(WRITE) [/RAS =H, /CAS = /WE =L] Precharge(PRE) [/RAS =L, /CAS =H,/WE =L] Auto-Refresh(REFA) [/RAS =/CAS =L, /WE =CKE =H] ACT command activates a row in an idle bank indicated by BA. READ command starts burst read from the active bank indicated by BA.Firs t output data appears after /CAS latency. When A10 =H at this command,the bank is deactivated after the burs t read(auto-precharge,READA). 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 burs t write(auto-precharge,WRITEA). PRE command deactivates the active bank indicated by BA. This command also terminates burst read / write operation. When A10 =H at this command, both banks are deactivated(precharge all, PREA). REFA command starts auto-refresh cycle. Refresh address including bank address are generated internally. After this command, the banks are precharged automatically. 7 |
