Abstract

Theft of memory in personal computers is becoming a major industry problem. Memory modules are very small and have a very high resale value. Therefore, professional thieves are stealing memory from corporations and selling the memory on the open market. Today, it is impossible to tell if memory is stolen or not and who the original owner was. This invention will make it more difficult to sell stolen memory on the open market.

Personal Computer Dual Inline Memory Module Memory Asset Protection

      Theft of memory in personal computers is becoming a major
industry problem.  Memory modules are very small and have a very high
resale value.  Therefore, professional thieves are stealing memory
from corporations and selling the memory on the open market.  Today,
it is impossible to tell if memory is stolen or not and who the
original owner was.  This invention will make it more difficult to
sell stolen memory on the open market.

This invention solves the following problems:
  1.  Prevent stolen memory from working in other
       systems.  Reduces incentive to steal memory.
  2.  Identify original owner of stolen memory.  Asset
       can be recovered and returned to rightful owner.

      New Joint Electron Device Engineering Council (JEDEC) standard
for Dual Inline Memory Modules (DIMMs) contains a Serial Electrically
Erasable Programmable Read-Only Memory (EPROM) for identification of
memory technology.  The current definition contains fields which
identify the memory supplier, technology, speed, etc..  We will
define a new field  which will be used for system identification.
Memory suppliers will always write 0's to this field.  System Basic
Input/Output System (BIOS)  on Power On Self Test (POST) time will
read this field.  If it contains  all 0's then the memory is valid
(never used in another system) and the system will write into this
field an unique value...
