Non-volatile semiconductor memory

A non-volatile semiconductor device has a memory cell array having electrically erasable programmable non-volatile memory cells, reprogramming and retrieval circuits that temporarily store data to be programmed in the memory cell array and sense data retrieved from the memory cell array. Each reprogramming and retrieval circuit has a first latch and a second latch that are selectively connected to the memory cell array and transfer data each other. A controller controls the reprogramming and retrieval circuits on data-reprogramming operation to and data-retrieval operation from the memory cell array. Each reprogramming and retrieval circuit has a multilevel logical operation mode and a caching operation mode. In the multilevel logical operation mode, re-programming and retrieval of upper and lower bits of two-bit four-level data is performed using the first and the second latches in storing the two-bit four-level data in one of the memory cells in a predetermined threshold level range. In the caching operation mode, data transfer between one of the memory cells selected in accordance with a first address and the first latch is performed while data transfer is performed between the second latch and input / output terminals in accordance with a second address with respect to one-bit two-level data to be stored in one of the memory cells.

Two-photon, three-or four-dimensional, color radiation memory

InactiveUS6483735B1Large storageEasy to getNanoinformaticsRecording involving hole burningDetector arrayPrism
Three-, and four-dimensional ("3-D" and "4-D") volume radiation memories store multiple binary bits of information-typically about five to ten and more typically eight such bits-in the same physical volumes on several different photochromic chemicals co-located in the volume. Each of the multiple photochromic chemicals is individually selectively written with an individually associated pair of radiation beams of an appropriate combined frequency-i.e., a "color"-and energy by a process of two-photon ("2-P") absorption. All the multiple information bits that are stored within all the photochromic chemicals in each addressable domain are read in common, and induced to simultaneously fluoresce, again by process of 2-P absorption. The fluorescence of each of different photochromic chemical in each addressed domain-which fluorescence is selective in accordance with the written state of each such photochromic chemical-is separated from, and is separately detected from, the fluorescence of all other photochromic chemicals because it is of a unique color, and is spatially steered to an associated detector array, normally a Charge Coupled Device (CCD), by a monochromator, normally a prism. Exemplary fluorescent photochromic chemicals are spirobenzopyran, rhodamine, cumarin and anthracene. Suitable groups of photochromic chemicals are formed from individual photochromic chemicals exhibiting narrow, sharp, separate spectra of absorption and of emission suitably distinct from each other, and where no chemical's fluorescent emission energy overlaps the absorption energies of any other chemicals.

The 3D NAND memory comprises multiple layers of storage arrays and multiple layers of control grid circuits, wherein each layer of the control grid circuit is electrically connected to the same layer of the storage array, so that selection of each layer of the storage array is realized; each layer of the control grid circuit is obtained by cascading a same number of transistors; grids of all the transistors of the control grid circuits are electrically connected to control wires; the number of the control wires is as the same as that of the transistors comprised in each layer of the control grid circuit; the grids of different transistors positioned on the same layer of the control grid circuit are electrically connected to different control wires. According to the 3D NAND memory, a small number of input control wires SSL select a large number of control grid layers through the control grid circuits, so that the area and the volume of the whole memory cannot be enlarged due to the increase of the number of the required layers of control grids when the storage capacity of the memory is improved due to the increase of the number of storage unit layers.
