8.3.11 User Memory Map

The EEPROM memory is organized as 8 pages of 4 blocks each. Figure 8-9 shows that each block is 8 bytes or

64 bits. This results in a total user memory of 2048 bits. All memory access to the device shall be increments of

a block size of 8 bytes. Access to the memory for programming is done through the scratchpad-2 register. The

host writes to the scratchpad-2 register, which allows the device to perform a read before committing the content

to the memory.
