SEMICONDUCTOR DISK DEVICE AND A RANDOM DATA PROCESSING METHOD THEREOF, CAPABLE OF IMPROVING RANDOM DATA ACCESS EFFICIENCY

摘要

PURPOSE: A semiconductor disk device and a random data processing method thereof are provided to realize random access for a plurality of data stored in locations through execution of one time random access command.;CONSTITUTION: When a random access type of the first type is selected, data is accessed by the first unit. At least part from the access result of the first unit is masked based on a setting result. When a random access type of the second type is selected, a random access operation of the second unit smaller than the first unit is consecutively performed based on the setting result. A masking result(80) is offered to a buffer memory. Output data(90) is offered from the buffer memory to a host.;COPYRIGHT KIPO 2010
