BIDIRECTIONAL COUNTER IN A FLASH MEMORY

摘要

A method of storing a counter in at least two non-volatile memory pages, including: a step of initializing a page with an initial value and then, on each update of the counter value, a step of storing an update value and an opcode associated with this value, selected from a set of opcodes, the current value of the counter being given by application of the successive update operations to the initial value of the page.

1. A method, comprising:
assigning at least two non-volatile memory pages of a memory to store counter value information; storing an initial counter value in a page of the at least two non-volatile memory pages; for each update of the stored initial counter value, storing an update value and an opcode associated with the update value in the page of the at least two non-volatile memory pages; and determining a current counter value based on the stored initial value, stored update values and stored opcodes.
