Abstract
A method for mitigating the effect of write disturbances in solid state memory. The method includes receiving a request to write to a memory location of the solid state memory, writing to the memory location, identifying a disturbed memory location, identifying a memory region that includes the disturbed memory location, identifying an address, in the memory region, of the disturbed memory location, generating an address hash from the address, and making a first determination that a history of disturbed memory locations in the memory region includes the address hash. The method further includes, based on the first determination, clearing the history of disturbed memory locations, making a second determination that a wear level operation is due, and based on the second determination, performing the wear level operation.
