摘要
A method for determining a retention time in a solid state device (SSD), comprising the steps of providing a plurality of write operations to a memory, determining a reference voltage for each of the write operations, determining a difference between (i) the reference voltage after each of the write operations and (ii) a target reference voltage and if the difference is above a predetermined value, generating a flag indicating an excessive retention has occurred.
