FLASH MEMORY READ ERROR RATE REDUCTION

摘要

An apparatus having a first circuit and a second circuit is disclosed. The first circuit may be configured to (i) generate a reference voltage used by a memory circuit in a first read of a set of data and (ii) adjust the reference voltage based on a plurality of parameters to lower an error rate in a second read of the set from the memory circuit. The second circuit may be configured to update the parameters in response to an error correction applied to the set after the first read from the memory circuit. The memory circuit is generally configured to store the data in a nonvolatile condition by adjusting a plurality of threshold voltages.
