摘要： A semiconductor memory device executes a writing operation based on a first bit assignment pattern at the time of writing. The first bit assignment pattern is created such that pieces of x-bit data assigned to adjacent threshold distributions have only a one-bit difference therebetween and an alignment of data on the same digit of 2x pieces of x-bit data corresponding to an alignment of 2x pieces of threshold distributions contains at least two transition points of “0” and “1”. The semiconductor memory device operates at the time of reading such that a read voltage corresponding to the transition points of “0” and “1” is applied to the word line on a page basis to determine x-bit data stored in the memory cell one-bit by one-bit based on the first assignment pattern. The page contains a set of data on the same digit bit in pieces of x-bit data stored in the memory cells connected to the word line.

摘要： A nonvolatile semiconductor memory for setting control voltages to be supplied to an internal circuit, to an external reference voltage inputted from outside, has a parameter control circuit. The parameter control circuit causes a parameter register to sequentially output the plurality of parameters to a voltage generating control circuit. The parameter control circuit counts, for a fixed period of time, the number of oscillations of each of the trimming flag signals sequentially outputted from the voltage generating control circuit in response to the parameters. The parameter control circuit stores counted values corresponding to the parameters. The parameter control circuit selects the parameter having a maximum counted value as a parameter corresponding to the control voltage closest to the external reference voltage.

摘要： An endless sliding guide apparatus including a track rail, a sliding table having an endless track comprising a load rolling path, a no-load rolling path and a change direction path and rolling bodies wherein at least one of the no-load rolling path, the inner peripheral portion of the change direction path and a rolling body retaining section of the load rolling path is formed by synthetic resin rolling body guide members formed by insert molding using a bearing race as a core. The rolling body guide members are molded by a synthetic resin composition satisfying the relational expression of (a.times.b).div.c.gtoreq.700 Mpa with respect to the tensile strength a (MPa), tensile elongation b (%) and shrinkage c (%). The endless sliding guide apparatus of the present invention has the advantages that since the endless track of the sliding table is accurately formed, the rolling of the rolling bodies along the endless track is quite smooth, the noise level is minimized and not only the manufacture of the sliding table can be automated but also the problem of "corner cracks" in the synthetic resin rolling body guide members can be eliminated thereby extending the working life of the apparatus.
