8 Read Operations

Read operations are initiated the same way as write operations with the exception that the Read/Write Select bit in the device address byte must be a logic ‘1’. There are three read operations:

  • Current Address Read
  • Random Address Read
  • Sequential Read
Note: All Read operations should be preceded by the SPA and/or RPA commands to ensure the desired half of the memory is selected. For example, during a sequential read operation on the last byte in the first half of the memory (address FFh) with SPA= 0 (indicating first half is selected), the internal address counter will rollover to address 00h in the first half of memory as opposed to the first byte in the second half of the memory. For more information on the SPA and RPA commands, see Set Page Address and Read Page Address Commands.
