... ROM or EPROM. Program commands are written to the Command Interface of the memory. An on-chip Program Con- troller (PC) simplifies the process of programming the memory by taking care of all of the special op- erations that are required to update the memory contents. The M27W064 features an innovative command, Multiple Word Program, used to program large streams of data ...

... Names, for a brief overview of the signals connect this device. Address Inputs (A0-A21). The Address Inputs select the cells in the memory array to access dur- ing Bus Read operations. During Bus Write opera- tions they control the commands sent to the Command Interface of the Program Controller. ...

... Electronic Signature. See Tables 2, Bus Opera- tions, for a summary. Typically glitches of less than 5ns on Chip Enable or Write Enable are ig- nored by the memory and do not affect bus opera- tions. Bus Read. Bus Read operations read from the memory cells, or specific registers in the Com- mand Interface ...

... Read mode. It has four phases: the Setup Phase to initiate the command, the Program Phase to program the data to the memory, the Verify Phase to check that the data has been correctly programmed and re- program if necessary and the Exit Phase. ...

... Address, FA (A17 or a higher address pin different from the Start Address), ends the Program Phase. The memory is now set to enter the Verify Phase. Verify Phase. The Verify Phase is similar to the Program Phase in that all Words must be resent to the memory for them to be checked against the programmed data ...

... Error Bit (DQ5). The Error Bit can be used to identify errors detected by the Program Controller. The Error Bit is set to ’1’ when a Program opera- tion fails to write the correct data to the memory. If the Error Bit is set a Read/Reset command must be issued before other commands are issued. The Error bit is output on DQ5 when the Status Regis- ter is read ...
