  • Patent number: 9064583
    Abstract: A Read Only Memory (ROM) and method for providing a high operational speed with reduced leakage, no core cell standby leakage, and low power consumption. The source of the ROM cell (NMOS) is connected to a virtual ground line (VNGD) instead of VSS. Thus, the ROM cell can be operatively coupled to the bit-line, the word-line, and the virtual ground, which also acts as a column select signal. The arrangement of the ROM is such that the virtual ground of the selected column is pulled down to a ground voltage. Non-selected columns virtual ground can be maintained at a supply voltage to ensure that unwanted columns will not have any sub-threshold current (as Vds=0). Since no pre-charging of bit-line comes in the access time path, the ROM achieves a high operational speed with reduced leakage and low power consumption.

  • Patent number: 8792293
    Abstract: Described embodiments provide a memory having at least one sense amplifier. The sense amplifier has a first capacitor, an inverting amplifier, a switch, an amplifier, and a second capacitor. The first capacitor is coupled between the input of the sense amplifier and a first node. The inverting amplifier has an input coupled to the first node and an output coupled to an internal node and the switch is coupled between the input and output of the inverting amplifier. The amplifier has an input coupled to the internal node and an output coupled to an output of the sense amplifier and the second capacitor is coupled between the internal node and a control node. When data is to be read from the memory, the second capacitor forces a small voltage reduction onto the intermediate node, helping the sense amplifier resolve the data value stored in the memory cell.
