Abstract: Disclosed herewith is a method for controlling the operation of non-volatile semiconductor chips with high sequential access performance realized by smoothing out the variation of the times for writing, erasing, and reading data in/from memory cells among sectors in each of the chips.

Abstract: A magnetic recording/reproducing apparatus includes a partial-response equalization circuit having frequency characteristic of cutting off low-frequency signal components inclusive of DC components; and a maximum-likelihood decoder, in which a reproduced signal outputted from the reproducing head is processed by the partial-response equalization circuit and then inputted into the maximum-likelihood decoder to be data-reproduced, thereby reducing a noise and distortion on the reproduced signal and reducing a data detection error rate.

Abstract: A magnetic recording disk drive can prevent the deterioration of the head off-track characteristics and the reduction of the drive performance even when an erase band asymmetry resulting from a skew angle exists. A write inhibit slice value for an inner peripheral side offset is made smaller than a write inhibit slice value for an outer peripheral side offset at a position where an erase band on the inner peripheral side is greater than an erase band on the outer peripheral side, so that the adjacent track on the outer peripheral side cannot easily erase a data track. On the contrary, the inner periphery and the outer periphery are paraphrased at a position where the erase band on the outer peripheral side is greater than the erase band on the inner peripheral side.

Abstract: The present invention provides a nonvolatile memory having a plurality of memory banks having a plurality of erasable and programmable nonvolatile memory cells and capable of memory operation independently respectively. The nonvolatile memory is capable of sequentially receiving write data and a write start command by the number of write processing regions after a write instruction command, a write start address and the number of the write processing regions with the write start address as a start point are inputted, latching write data for one write processing region in one memory bank and thereafter starting writing to each memory cell in response to the write start command, and making parallel a latch operation at one memory bank and writing to each memory cell at other memory banks.

Abstract: A magnetic disk drive has a low power consumption state in which the spindle motor is stopped for reducing the average power consumption when no read or write commands have been received. When a read or write command is received, the spindle motor is started. The time it takes to complete a read command is shorter than that for a write command as measured from the receipt of the read command or write command with the spindle motor stopped in the low power consumption state.

Abstract: Two embodiments of corrugated paper shipping boxes that can be knocked down into a flat form and in which a cradle support is also formed by corrugated paper for holding the shipped article away from the sides of the box. In one embodiment, the cradle is formed by extensions of the end flaps of the end walls of the box and in another embodiment, the cradle is formed as a separate assemblage also from corrugated paper and adapted to be folded into a flat configuration. This facilitates storage and disposal and eliminates the use of foamed plastic insert pieces.
