  • Patent number: 7782705
    Abstract: A word line decoder circuit is provided in the present invention. The word line decoder circuit comprises at least one local pre-decoder, at least one 3-transistors row driver, a controllable power supply, and a controllable pull-down circuit. The controllable power supply is controlled by an inversed sector select signal to provide a first voltage to the row driver and local pre-decoder. The local pre-decoder uses 5-transistors architecture, in which there are 2 PMOS transistors and 3 NOS transistors. The controllable pull-down circuit pulls down the local pre-decoder and is controlled by a sector select signal and pre-decoding signal. The local pre-decoder receives a local pre-decoding signal to select the row driver. When the row driver is selected, the row driver determines a word line according to a row driver pull-down signal and a row driver pull-up signal.

  • Patent number: 7746721
    Abstract: A sector of a word line driver circuit is provided, comprising a local reset signal generator module and m word line clusters. The m word line clusters are coupled to the local reset signal generator module. The local reset signal generator module is used to generate j reset signals. The x-th reset signal is determined according to an x-th pre-decoding signal, a bank selectable signal and a sector selectable signal, wherein j is a nature number, and x is an integer from 1 to j. Each of the m word line clusters comprises j row drivers. The x-th row driver of the y-th word line cluster determines a [x+j*(y?1)]-th word line signal according to the x-th reset signal, the x-th pre-decoding signal, the sector selectable signal, and a y-th cluster select signal, wherein m is a nature number, and y is an integer from 1 to m.

  • Publication number: 20050125622
    Abstract: When the memory device receives address information and byte information M, the memory device continuously provides M bytes corresponding to M addresses following an address assigned in the address information. The memory device includes: an address calculation module, an address buffer, a decoding module, a plurality of memory units and output buffers. Each output buffer is capable of receiving data of two units and sequentially outputting the data. When the address calculation module stores an address in the address buffer, the decoding module makes cells corresponding to the address simultaneously output data to the output buffers, such that the output buffers sequentially output data of respective unit. The address calculation module starts to count the next address, such that when the output buffer finishes outputting, the next address is already stored in the address buffer, and the decoding module has already made units corresponding to the next address output data.
