    摘要: A coordinate input apparatus comprises: a vibration pen to generate a vibration; a vibration propagating plate to propagate the vibration generated by the pen by touching the pen to the plate; vibration sensors to detect the vibration propagated to the plate; a supporting member which supports the plate and whose vibration propagating velocity is slower than the plate; a position coordinate calculating circuit to calculate the position coordinates of the pen on the plate on the basis of the detection signals from the sensors; and a display which is provided below the supporting member and displays the calculated coordinates. The plate is made of metal or transparent glass and the supporting membrr is made of a transparent synthetic resin. The supporting member is directly in contact with the plate at a rough surface, its acoustic impedance value is different from the plate, and its vibration attenuation ratio is larger than that of the plate. Since the vibration wave component propagated to the sensors is not influenced by the interference of the vibration propagated in the support member, the coordinates can be accurately detected on the basis of the vibration detection waveforms without distortion.

    摘要: In the control of the number of program-erase cycles, physical blocks (PBs) are divided into plural groups on a basis of the number of program-erase cycles and a search for a free PB is performed in the groups when assigning a logical block (LB) to the free PB. In the search, a free PB among a group covering a small number of program-erase cycles precedes that among a group covering a large number of program-erase cycles. Further, when searching out a free PB in the search, data stored in a PB (source PB) included in a group covering a smaller number of program-erase cycles than that covered by a group including the free PB searched out are transferred to the free PB if there is the source PB. The source PB is a PB to which a LB is assigned earliest among a group including it.

    摘要: First operations and second operations are performed in parallel. The first operations are operations to write first data to a first unit area which is any one of unit areas. The second operations are operations to read second data corresponding to the same logical page as first data from one or more flash memories and write the second data to a second unit area which is any one of the unit areas and different from the first unit area. Data transfer is performed between the first unit area and the second unit area so as to form data composed of the first data and a portion of the second data which is not replaced with the first data.
