A method for controlling wear level operations in solid state memory. The method includes receiving a request to write to a memory location identified by a write address of the solid state memory, generating a write address hash from the write address, making a first determination that a write history for a memory region includes the write address hash, and based on the first determination: clearing the write history, storing the write address hash in the write history, and making a second determination that a wear level operation is due, and based on the second determination: performing the wear level operation.
