System and method to enable reading from non-volatile memory devices

摘要

A system and method to enable reading from non-volatile memory (NVM) devices is described. In one embodiment, the method includes setting a sensing parameter used to read data stored in a NVM device, reading from pluralities of locations of the NVM device with the sensing parameter set at the first value. The locations of the NVM device store an identical value. The method also includes verifying whether the identical value is read correctly from the locations of the NVM device. The method also includes setting the sensing parameter to a second value when the identical value is not read correctly with the sensing parameter set at the first value. The method further includes determining a third value for the sensing parameter from the identical value and setting the sensing parameter to the third value when the identical value is read correctly.

1. A method, implemented by a computing system programmed to perform the following, comprising:
setting a sensing parameter, used to read data stored in a non-volatile memory (NVM) device, to a first value; reading a data value from each of a plurality of locations of the NVM device with the sensing parameter set at the first value, wherein the data value from each of the plurality of locations of the NVM device comprises a plurality of bits and is an identical value, wherein the identical value represents a configuration parameter for the NVM device; verifying whether the identical value is read correctly from the plurality of locations of the NVM device; setting the sensing parameter to a second value when the identical value is not read correctly with the sensing parameter set at the first value; and when the identical value is read correctly,
determining a third value for the sensing parameter from the identical value, andsetting the sensing parameter to the third value when the identical value is read correctly.
