  • Patent number: 8982636
    Abstract: A memory comprises a memory cell, a sense amplifier, and a control unit. The memory cell stores a first bit and a second bit. The sense amplifier senses a first cell current and a second cell current corresponding to the first and the second bits respectively with a voltage applying on the memory cell. The control unit determines a digital state of the first bit by comparing a first reference current with the first cell current or by comparing a reference data with a first delta current between the first cell current and the second cell current.

  • Patent number: 8345476
    Abstract: A method of storing data in a multi-level charge-trapping memory array is described. An incidence-of-occurrence (i.e., frequency) analysis is performed on data to be programmed to identify data words combining a high programming voltage with a high frequency of occurrence. Those words are reassigned in order to reduce programming time.

  • Patent number: 8238166
    Abstract: Methods are disclosed to compensate for a second-bit effect during programming and reading of charge-trapping memory cells having left and right data regions. When only one of the left and right data regions is to be programmed, a two-step programming procedure is performed on the data region to be programmed. When the memory cell is to be read, threshold voltages for the left and right data regions are sensed with a joint decision regarding left and right data bit values being reached depending upon both sensed threshold voltage values.

  • Patent number: 8207451
    Abstract: A ground-plane slotted type signal transmission circuit board is proposed, which is designed for use with a high-speed digital signal processing system for providing a low-loss signal transmission function. The proposed circuit board structure is characterized by the formation of a slotted structure (i.e., elongated cutaway portion) in the ground plane at the beneath of each signal line. Since the slotted structure is a void portion, the electric field of a gigahertz signal being transmitting through the overlaying signal line would be unable to induce electric currents in the void portion of the ground plane. This feature allows the prevention of a leakage current that would otherwise flow from the signal line to the ground plane, and therefore can help prevent unnecessary power loss of the transmitted signal.

  • Patent number: 8164958
    Abstract: The invention provides a method for reading a first data storage of a memory cell. The method comprises sensing a first current of the memory cell by applying a first bit line voltage on the memory cell. When the first current is larger than a first reference current with respect to the first bit line voltage, the first data storage is determined to be at an un-programmed state. Otherwise, a second current of the memory cell is sensed by applying a second bit line voltage on the memory cell. When the difference between the first current and the second current is larger than the difference between the first reference current and the second reference current, the first data storage is determined to be at the un-programmed state. Otherwise, the first data storage is determined to be at a programmed state.
