Abstract: An error recovery procedure (ERP) in a storage device such as a rotating magnetic hard disk drive is executed to the last step regardless of the established time-out period for an instruction, thereby more reliably recovering from errors. In accordance with one embodiment of the invention, when a disk drive receives a reset instruction from a host during the execution of an ERP, it executes the ERP until the error is recovered, or to the last step without interrupting the ERP. Further, in accordance with another embodiment of the invention, when a disk drive receives a reset instruction during the execution of an ERP, it stops execution of the ERP and holds the number K of the step which was completed immediately before stopping, and when receiving a retry instruction after that, sequentially executes the ERP from the K+1-th error recovery step.

Abstract: PROBLEM TO BE SOLVED: To provide a memory controller, a chip and a method for performing data transfer to an LCD (liquid crystal display) so that disturbance is not generated in the display of the LCD.
SOLUTION: A chip 10 is constituted so that a DRAM (dynamic random access memory) controller (memory controller) 14 includes a dither circuit 15 for performing dither processing in order to reduce the data amount of data at the time of performing the storing or reading of data.

Abstract: PROBLEM TO BE SOLVED: To provide a method/device which can assure execution of an ERP (error recovery procedure) up to its last step regardless of the time needed up to the time-out of an instruction and can more surely recover an error. SOLUTION: A disk device carries out an ERP up to its last step or until an error is recovered with no interruption when a reset instruction is received during execution of the ERP. In another mode, the disk device stops execution of the ERP and also holds the number K of the step whose execution is over right before reception of a reset instruction when this instruction is received during execution of the ERP. Then the disk device successively carries out the ERP from the (K+1)th error recovery step when a retry instruction is received.
