摘要:
There is provided a nonvolatile semiconductor storage device capable of securing sufficient read accuracy without providing superfluous sense time margin when there are variations in temperature and transistor characteristics. This nonvolatile semiconductor storage device includes a reference cell 2 whose threshold value is preparatorily set to a value between a lower limit of a threshold voltage distribution in a state 0 in which nonvolatile memory cells MC00 through MC12 have a high threshold value and an upper limit of a threshold voltage distribution in a state 1 in which the memory cells have a low threshold value. When the characteristics of the nonvolatile memory cells MC00 through MC12 shift due to the influence of a change in temperature or the like, the characteristics of the reference cell 2 shift so as to follow this characteristic shift. The operation timing of a sense amplifier section 8 in read operation is generated by a control circuit, and the timing of the termination of the sense operation from among the operation timing is determined by timing control circuit (delay circuit delay and AND circuits AN0 and AN1) with the termination of the sense of the reference cell 2.

A modified polyacetal is obtainable by heating 0.1 to 30 parts by weight of (B) a polymerizable compound having a modifying group such as an epoxy group, a carboxyl group or an acid anhydride group relative to 100 parts by weight of (A) a base polyacetal and introducing the modifying group of the polymerizable compound to the base polyacetal. The base polyacetal (A) includes (A1) a polyacetal selected from polyoxymethylene homopolymers and copolymers, and (A2) a polymerizable polyacetal having a functional group comprising a polymerizablly unsaturated bond. The introduction efficiency of the modifying group can be enhanced by adding 0.01 to 2.5 parts by weight of (C) a free-radical initiator relative to 100 parts by weight of the total amount of the components (A) and (B), and mixing the resultant mixture under a molten state of the polyacetal. According to such method, the affinity of the polyacetal is improved by introducing the modifying group to the base polyacetal with ease and high efficiency.

To prepare a thermally very stable polyacetal copolymer containing a very small amount of unstable parts in a high yield according to a simple process wherein an isopolyacid or an acid salt thereof is used as the polymerization catalyst in the copolymerization of trioxane as the principal monomer with a comonomer copolymerizable therewith, and wherein deactivation of the catalyst can be effected simply without fail through contact with a basic gas after polymerization without the necessity for any washing step. In the preparation of a polyacetal copolymer by the copolymerization of trioxane as the principal monomer with a cyclic ether or cyclic formal having at least one carbon--carbon bond as a comonomer, the copolymerization is effected using an isopolyacid or an acid salt thereof as the polymerization catalyst, followed by contact with a basic gas as a deactivator to deactivate the catalyst, and subsequent heat-melting treatment of the resulting crude polymer intact without washing thereof.
