Abstract: A memory wherein the bit reliability of the memory cells can be dynamically varied depending on the application or the memory status, the operation stability is ensured, and thereby a low power consumption and a high reliability are realized. Either a mode (a 1-bit/1-cell mode) in which one bit is composed of one memory cell or a mode (a 1-bit/n-cell mode) in which one bit is composed of n (n is two or more) connected memory cells is dynamically selected. When the 1-bit/n-cell mode is selected, the read/write stability of one bit is enhanced, the cell current during read is increased (read is speeded up), and a bit error, if occurs, is self-corrected. Especially, a pair of CMOS transistors and a control line for performing control so as to permit the CMOS transistors to conduct are added between the data holding nodes of n adjacent memory cells. With this, the word line (WL) is controlled, and thereby the operation stability is further improved.

Abstract: We paid attention to stearoyl-CoA desaturase gene, and investigated the relation between this gene and the unsaturated fatty acid content in beef fat. As a result, we found that the unsaturated fatty acid content was associated with the genotype of this gene, classified according to several single nucleotide polymorphisms (SNPs) on this gene. The present invention is a method to predict the unsaturated fatty acid content in beef (or milk) fat, on the basis of the genotype of bovine stearoyl-CoA desaturase, and useful prediction method for beef quality such as taste and texture.

Abstract: Noise measuring circuitry of the present invention can be used to observe power supply noise waveforms, ground level noise waveforms, and a spatial distribution of noise at different positions in an integrated circuit having plural circuit blocks that perform digital signal processing, by being integrated into the integrated circuit (i.e., embedded), distributed at different positions. The distributed noise measuring circuitry can be manufactured using a CMOS process to manufacture the integrated circuit. The power supply noise measuring circuit and the ground level noise measuring circuit comprise a source follower, a select read out switch, and source-grounded amplifier. These noise measuring circuits can be configured by several (about 6) MOS transistors, so the layout for the measuring circuit can be small and can be achieved by using a logic gate circuit of the same size as that of a standard cell type logic gate circuit.

Abstract: By focusing attention on SREBP-1 gene, the relationship between this gene and the degree of unsaturation in beef body fat is examined. As a result, it is found out that this gene occurs as an “L-type” gene having a longer fifth intron and an “S-type” gene having a fifth intron shorter by 84 bases than the above one and these genotypes relate to the degree of unsaturation in beef body fat. A method of evaluating the content of unsaturated fatty acids in beef body fat based on these SREBP-1 genotypes is applicable to the evaluation of beef taste, texture and so on and, therefore, is industrially useful.
