Document Type and Number:
WIPO Patent Application WO/2017/119995
Kind Code:
A3
Abstract:
In a non-volatile memory system, a fast bulk secure erase method for erasing data includes, in response to a secure erase command: applying charge to a portion of non-volatile memory in the non-volatile memory system, and performing an erase operation sufficient to remove charge from the portion of non-volatile memory to below an erase threshold. The applied charge is sufficient to program memory cells in the portion of non-volatile memory to above a pre-erase program threshold.
