Abstract
A data storage device includes a resistive random access memory (ReRAM). The data storage device includes read circuitry coupled to a storage element of the ReRAM. The read circuitry is configured to read a data value from the storage element, during a read operation, based on a read current sensed during a first phase of the reading operation and a leakage current sensed during a second phase of the reading operation. The data storage device also includes a controller coupled to the read circuitry. The controller is configured to provide an input value to an error correction coding (ECC) decoder, where the input value includes a hard bit value and a soft bit value. The hard bit value corresponds to the data value, and the soft bit value is at least partially based on the leakage current.
