Abstract:
A read method in a flash memory system containing a flash memory and a memory controller includes updating a selected one of indexes of a selected one of blocks of the flash memory, in a wear-out table for indexing each of the blocks of the flash memory, and setting a start read level to start read retry on the selected block by referring to a read retry table corresponding to a wear-out degree included in the selected index when a current request of read retry on the selected block is received.

Abstract:
A developing unit employing a two-component developing agent is shown. The developing unit includes a first regulating member, a second regulating member, and a third regulating member forming first, second, and third regulating gaps respectively with a developing roller. The third regulating member forms a recovery path for recovering excessive developing agent that may not pass through the first and second regulating gaps to an agitating region between the third and second regulating members. A distance between a vertical line passing through an upstream side end portion of the second regulating member based on a rotating direction of the developing roller and a center of the developing roller is greater than a radius of the developing roller, and a downstream end of the third regulating member is located between a regulating pole and a catch pole.
