14 / 70 page  M58CR064C, M58CR064D, M58CR064P, M58CR064Q 14/70 s The second latches the block address in the internal state machine and starts the Program/ Erase Controller. If the second bus cycle is not Write Erase Confirm (D0h), Status Register bits SR4 and SR5 are set and the command aborts. Erase aborts if Reset turns to VIL. As data integrity cannot be guaran- teed when the Erase operation is aborted, the block must be erased again. Once the command is issued the device outputs the Status Register data when any address within the bank is read. At the end of the operation the bank will remain in Read Status Register mode un- til a Read Array, Read CFI Query or Read Elec- tronic Signature command is issued. During Erase operations the bank containing the block being erased will only accept the Read Sta- tus Register and the Program/Erase Suspend command, all other commands will be ignored. Refer to Dual Operations section for detailed infor- mation about simultaneous operations allowed in banks not being erased. Typical Erase times are given in Table 14, Program, Erase Times and Pro- gram/Erase Endurance Cycles. See Appendix C, Figure 24, Block Erase Flow- chart and Pseudo Code, for a suggested flowchart for using the Block Erase command. Program Command The memory array can be programmed word-by- word. Only one Word in one bank can be pro- grammed at any one time. Two bus write cycles are required to issue the Program Command. s The first bus cycle sets up the Program command. s The second latches the Address and the Data to be written and starts the Program/Erase Controller. After programming has started, read operations in the bank being programmed output the Status Register content. During Program operations the bank being pro- grammed will only accept the Read Status Regis- ter and the Program/Erase Suspend command. Refer to Dual Operations section for detailed infor- mation about simultaneous operations allowed in banks not being programmed. Typical Program times are given in Table 14, Program, Erase Times and Program/Erase Endurance Cycles. Programming aborts if Reset goes to VIL. As data integrity cannot be guaranteed when the program operation is aborted, the memory location must be reprogrammed. See Appendix C, Figure 20, Program Flowchart and Pseudo Code, for the flowchart for using the Program command. Program/Erase Suspend Command The Program/Erase Suspend command is used to pause a Program or Block Erase operation. A Bank Erase operation cannot be suspended. One bus write cycle is required to issue the Pro- gram/Erase Suspend command. Once the Pro- gram/Erase Controller has paused bits SR7, SR6 and/ or SR2 of the Status Register will be set to ‘1’. The command must be addressed to the bank containing the Program or Erase operation. During Program/Erase Suspend the Command In- terface will accept the Program/Erase Resume, Read Array (cannot read the suspended block), Read Status Register, Read Electronic Signature and Read CFI Query commands. Additionally, if the suspend operation was Erase then the Clear status Register, Program, Block Lock, Block Lock- Down or Protection Program commands will also be accepted. The block being erased may be pro- tected by issuing the Block Lock, Block Lock- Down or Protection Register Program commands. Only the blocks not being erased may be read or programmed correctly. When the Program/Erase Resume command is issued the operation will complete. Refer to the Dual Operations section for detailed information about simultaneous opera- tions allowed during Program/Erase Suspend. During a Program/Erase Suspend, the device can be placed in standby mode by taking Chip Enable to VIH. Program/Erase is aborted if Reset turns to VIL. See Appendix C, Figure 23, Program Suspend & Resume Flowchart and Pseudo Code, and Figure 25, Erase Suspend & Resume Flowchart and Pseudo Code for flowcharts for using the Program/ Erase Suspend command. Program/Erase Resume Command The Program/Erase Resume command can be used to restart the Program/Erase Controller after a Program/Erase Suspend command has paused it. One Bus Write cycle is required to issue the command. The command must be written to the bank containing the Program or Erase Suspend. The Program/Erase Resume command changes the read mode of the target bank to Read Status Register mode. If a Program command is issued during a Block Erase Suspend, then the erase cannot be re- sumed until the programming operation has com- pleted. It is possible to accumulate suspend operations. For example: suspend an erase oper- ation, start a programming operation, suspend the programming operation then read the array. See Appendix C, Figure 23, Program Suspend & Re- sume Flowchart and Pseudo Code, and Figure 25, Erase Suspend & Resume Flowchart and Pseudo |
