Security for memory module data

摘要

A memory module contains a set of contacts configured to contact a second set of contacts on a memory module connector when the memory module is removed from the connector. The contacts on the connector can be activated. The memory module is configured to erase data on the memory module in response to the set of contacts on the memory module contacting the set of contacts on the connector when the set of contacts on the connector is activated.

主权项

1. A memory module comprising:
one or more dynamic random access memory (DRAM) chips; a first set of contacts on a face of the memory module, the first set contacts configured to contact a second set of contacts on an inner surface guide of a memory module connector when the memory module is removed from the connector, the memory module connector connecting the memory module to a computer system, the memory module connector configured to receive the memory module and comprising an electrically-actuated pin configured to lock the memory module into the memory module connector in response to receiving a request to provide authentication protection from the computer system; a slot configured to receive the electrically-actuated pin; erase procedure circuitry, the erase procedure circuitry configured to erase at least one of the one or more DRAM chips in response to the first set of contacts contacting the second set of contacts when the second set of contacts are activated, the second set of contacts activated in response to receiving the request to provide authentication protection; and a battery configured to supply power to the erase procedure circuitry in response to the first set of contacts contacting the second set of contacts when the second set of contacts are activated.
