Additional preview pages of the DS1982 datasheet.

1024 bits Electrically Programmable ReadOnly Memory (EPROM) communicates with the economy of one signal plus ground.
EPROM partitioned into four 256-bit pages for randomly accessing packetized data.
Each memory page can be permanently writeprotected to prevent tampering.
Device is an “add only” memory where additional data can be programmed into EPROM without disturbing existing data.
Architecture allows software to patch data by superseding an old page in favor of a ne.
