FUNCTION
Input Master Clock:All other inputs referenced rising edge Clock Enable:CKE controls internal clock.When low,internal clock following cycle ceased. also used select auto self refresh. After self refresh mode started, becomes asynchronous input.Self refresh maintained long low. Chip Select: When high,any command means Operation. Combination /RAS,/CAS,/W defines basic commands. A0-11 specify Row/Column Address conjunction with BA.The Address specified A0-11.The Column Address specified A0-10.A10 also used indicate precharge option.When high read write command, auto precharge performed. When high precharge command, both banks precharged. Bank Address:BA0,1 simply BA.BA0,1 specifies bank which command applied.BA must with ACT,PRE,READ,WRITE commands

BASIC FUNCTIONS
MH32S72QJA provides basic read write, bank(row)precharge,and auto self refresh. Each command defined control signals /RAS,/CAS rising edge. addition signals,/S,CKE used chip select,refresh option,and precharge option,respectively. know detailed definition commands please command truth table.

Activate(ACT) [/RAS /CAS command activates idle bank indicated Read(READ) [/RAS =H,/CAS READ command starts burst read from active bank indicated BA.First output data appears after /CAS latency. When this command,the bank deactivated after burst read(auto-precharge,READA). Write(WRITE) [/RAS /CAS WRITE command starts burst write active bank indicated Total data length written burst length. When this command, bank deactivated after burst write(auto-precharge,WRITEA). Precharge(PRE) [/RAS /CAS =H,/WE command deactivates active bank indicated This command also term inates burst read write operation. When this command, both banks deactivated(precharge all, PREA). Auto-Refresh(REFA) [/RAS =/CAS =CKE PEFA command starts auto-refresh cycle. Refresh address including bank address generated internally. After this command, banks precharged automatically.

POWER SEQUENCE
Before tarting normal operation, following power sequence necessary prevent SDRAM from damaged malfunctioning. Apply power start clock. Attempt maintain high, DQMB high condition inputs. Maintain stable power, stable cock, input conditions inimum 500µs. Issue precharge commands banks. (PRE PREA) After banks become idle state (after tRP), issue more auto-refresh commands. Issue mode register command initialize mode register. After these sequence, SDRAM idle state ready normal operation.
MODE REGISTER
Burs Length, Burst Type /CAS Latency programmed setting mode register(MRS). mode register stores these date until next command, which issue when both banks idle state. After tRSC from command, SDRAM ready command.
