  • Patent number: 11966628
    Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.

  • Patent number: 7718713
    Abstract: A method of manufacturing super-absorbent polymer (SAP) which is powdery, insoluble in water, and able to absorb water, blood and urine with slight soluble substances. The method includes at least the following steps: mixing a monomer solution having at least 50 mol % of neutralized acrylic acid with polymerization initiators to synthesize a sticky precursor, wherein the monomer can be selected from acrylic acid, methacrylic acid, 2-acrylamido-2-methyl-propane sulfonic acid, or the mixtures thereof; mixing high hydrophilic epoxy compounds and polymerization initiators with the precursor and producing a gel via UV cross-linking; drying the gel at temperature of 100 to 250° C. to obtain a polymer; grinding and screening the polymer into constant particle size; coating the polymer with surface cross-linking agents; heating the polymer at temperature of 80 to 230° C.; and adding powdery inert inorganic salts into the polymer.
