Abstract: The invention intends to provide a memory card conforming to an HS-MMC mode in a standard of a multimedia card, while securing compatibility of both standards of the multimedia card and an SD card. In a normal MMC mode, the data is outputted at a fall edge of a clock signal. A frequency of the clock signal is about 20 MHz. When the data is outputted at the fall edge of the clock signal, data output is in time for a next clock signal. When a parameter ‘1’ is set to a timing register provided in a host interface, the memory card is transitioned into the HS-MMC mode. In the HS-MMC mode, a clock signal frequency is increased to about 52 MHz. Here, the data is outputted at the rise edge of the clock signal, whereby the data output is brought in time for the rise edge of the next clock signal.

Abstract: A first ball circulating hole and a second ball circulating hole for connecting a circulator are bored midway at a screw groove formed on an inner circumference of a ball nut, an intermediate groove path between the first and second ball circulating holes becomes the range of a ball screw track for circulating balls, and other ranges become a first outer track and a second outer track which are not the ball screw track. By making the groove depth of the intermediate groove path deeper than the groove depth of a first groove path of the first outer track and the groove depth of a second groove path of the second outer track, steps are formed between the ball screw track and the two outer tracks. These steps prevent an outflow of the balls from the intermediate groove path to the respective groove paths of the outer tracks.

Abstract: To prevent stored information from being changed even at the occurrence of an abnormal condition in an upstream side of a system due to uncontrollable run of an OS. A nonvolatile storage means having data storage areas and management areas for them in units of predetermined physical addresses has an access protect definition table TLB in a predetermined physical address, and the table has access attribute information defining whether to permit or not access to the data storage areas in association with the physical addresses. The memory system itself possesses access attribute information defining whether to permit or not a write to and a read from the data storage areas in association with addresses to implement an access protect function for write and read. Therefore, the access protect function is maintained even if an abnormal condition occurs in a host device that manages the memory system or controls it as a peripheral circuit.

When the processing result and the expected value matches with each other, the aforementioned area is determined as being in a normal condition.

Abstract: When a storage section is installed in a controller and the controller is installed in an access device, the controller reads out device ID data and CIS data from the storage section, and certifies the storage section based on the device ID data and the CIS data. Upon completion of the certification of the storage section, the controller reads out boot data and a code key therefrom, and supplies the access device with the read boot data and code key. Subsequently, the access device decodes general data read out from the storage section via the controller, using the code key, and encodes data to be stored using the code key, and writes the encoded data in the storage section via the controller.
