ABSTRACT:
A method of initiating and controlling background clean-up of a solid state memory disk is described. Background clean-up begins by enabling a clean-up state machine after completion of a write command. Next, a next state pointer is set to an initial state for evaluating whether clean-up is necessary. Actual execution of background clean-up begins when the processing unit allocates execution time for clean-up. As each state is executed, the next state pointer is reset so that it points to the next clean-up state to be executed. States pointed to by the next state pointer are executed until a block of the solid state memory disk is cleaned-up.
Also described is a method of automatically performing foreground clean-up of a solid state memory disk. A method of forcing clean-up is also described.
