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.
