Abstract
A method and apparatus for reading a flash memory device are disclosed. A Regression Neural Network (RNN) inference model is stored on a flash controller. The RNN inference model is configured for identifying at least one Threshold-Voltage-Shift Read-Error (TVS-RE) curve that identifies a number of errors as a function of Threshold Voltage Shift Offset (TVSO) values. The operation of a flash memory device is monitored to identify usage characteristic values. A neural network operation of the RNN inference model is performed to generate a TVS-RE curve corresponding to the usage characteristic values. The input for the neural network operation includes the usage characteristic values. A TVSO value is identified corresponding to a minimum value of the TVS-RE curve. A read of the flash memory device is performed using a threshold-voltage-shift read at the TVSO value.
