MEMORY MAP
The DS2406 has two memory sections, called data memory and status memory. The data memory
consists of 1024 bits of one-time programmable EPROM organized as 4 pages of 32 bytes each. The
address range of the device’s status memory is 8 bytes. The first seven bytes of status memory (addresses
0 to 6) are implemented as EPROM. The eighth byte (address 7) consists of static RAM. The complete
memory map is shown in Figure 5. The 8-bit scratchpad is an additional register that acts as a buffer when
writing the memory. Data is first written to the scratchpad and then verified by reading a 16-bit CRC
from the DS2406 that confirms proper receipt of the data and address. This process ensures data integrity
when programming the memory. If the buffer contents are correct, the bus master should transmit a
programming pulse (EPROM) or a dummy byte FFh (RAM) to transfer the data from the scratchpad to
the addressed memory location. The details for reading and programming the DS2406 are given in the
Memory Function Commands section.
