    摘要: The present invention relates to a ball chain used by being integrated to, for example, a ball endless track of a linear guide device for endless sliding in which a number of balls are arranged in one row and rollably held, particularly to a ball chain which is most pertinent to a linear guide device having a ball rolling groove in a shape of a Gothic arch. According to the ball chain, the number of balls are arranged in one row and the balls are held rollably, each of the balls is pinched by a pair of spherical seats and the spherical seats are connected to each other by flange portions to thereby constitute a ball holding unit and a plurality of the ball holding units are connected in a shape of a rosary by a flexible connecting portion. Further, the spherical seats and the flange portions are molded by a resin material whereas the connecting portion is formed by a material having a tensile strength larger than that of the resin material.

    摘要: In a memory cell array, memory cells enabled to store plural-bit data are arranged in matrix. The bit-line control circuit is connected to bit-lines to control the bit-lines. A word line control circuit applies a plural-bit data read voltage as a word line voltage to the word line. The plural-bit data read voltage is larger than an upper limit of one of plural threshold voltage distributions and smaller than a lower limit of another threshold voltage distribution. Furthermore, it applies a soft-value read voltage as a word line voltage to the word line. The soft-value read voltage is smaller than an upper limit of a threshold voltage distribution and larger than a lower limit thereof. The likelihood calculation circuit calculates likelihood of the plural-bit data stores in the memory cells based on the soft-value.

    摘要: A write controller performs verification for checking whether each memory cell is on a predetermined verification level. For a memory cell to be written to a voltage level higher than the predetermined verification level, the write controller stores, in first and second latch circuits, the number of times of write to be performed by a write voltage after the verification. Whenever write is performed by the write voltage, the write controller updates the number of times of write stored in the first and second latch circuits. After write is performed the number of times of write by the write voltage, the write controller performs write by an intermediate voltage lower than the write voltage.
