METHOD OF ERASING INFORMATION STORED IN NONVOLATILE REWRITABLE MEMORY, STORAGE MEDIUM AND MOTOR VEHICLE COMPUTER Russian patent published in 2017 - IPC G06F12/02 G11C16/16 

FIELD: data processing.

SUBSTANCE: group of inventions relates to data storage and can be used for deleting information stored in nonvolatile rewritable computer memory. Method includes preliminary steps of determining a virtual memory addressing space, associated with memory, in which each sector extends over a specific range of consecutive virtual memory addresses, and a step of establishing a first correspondence function for determining, from a range of virtual memory addresses, sector or sectors whose contents must be erased. Method also includes, for each erasing request received by a slave module indicating a range of virtual memory addresses, a step of determining sector or sectors whose contents must be erased by slave module. Memory comprises plurality of segments (S1, S2), broken down into a plurality of sectors and two segments comprise interleaved physical memory addresses, each erasing request sent by master module is sent indicating a range of virtual memory addresses corresponding only to a single segment of memory. Two consecutive erasing requests sent by master module respectively indicate ranges of virtual memory addresses corresponding to different segments of memory, said two consecutive erasing requests are aimed respectively at first segment (S1) and second segment (S2), corresponding erasing operations taking place in parallel.

EFFECT: reduced risks of erroneous erasing of sectors containing interleaved physical memory addresses.
