Scratch EEPROM
Also available in the memory component on the processor SMBus is an EEPROM which may be
used for other data at the system or processor vendor’s discretion. The data in this EEPROM, once
programmed, can be write-protected by asserting the active-high SM_WP signal. This signal has a
weak pull-down (10 K
) toallow the EEPROM tobe programmedin systems with no
implementation of this signal. The Scratch EEPROM resides in the upper half of the memory
component (addresses 80 - FFh). The lower half comprises the Processor Information ROM
(address 00 - 7Fh), which is permanently write protected by Intel.
