  • Patent number: 9940988
    Abstract: A method of controlling a wordline by a driver decoder circuit includes generating a first control signal having a first logically high level and a first logically low level, and generating a second control signal having a second logically high level when the first control signal has the first logically high level and a second logically low level when the first control signal has the first logically low level. The first logically high level is different from the second logically high level, and the first logically low level is different from the second logically low level. The method includes coupling the wordline to a first node having a first voltage value in response to the first control signal having the first logically low level and decoupling the wordline from a second node having a second voltage value in response to the second control signal having the second logically low level.

  • Patent number: 9224446
    Abstract: A memory circuit includes first and second word lines, a plurality of memory cells and a timing controller. Each memory cell includes a first access port and a second access port. The first access port is coupled to the first word line and configured to be enabled by a first word line signal on the first word line. The second access port is coupled to the second word line and configured to be enabled by a second word line signal on the second word line. The timing controller is configured to receive a timing select signal and to control a time delay between the first word line signal and the second word line signal to be different in response to different first and second states of the timing select signal.

  • Patent number: 7779334
    Abstract: An error correction code system for a memory having parity columns of a memory array located within the memory array is provided. The parity columns are grouped together or distributed throughout the memory array. An embodiment includes a multiplexor circuit for selectively coupling only parity bits stored in the parity memory array to I/O circuitry, bypassing ECC logic circuitry and allowing the parity columns to be directly accessible, in a direct access mode or for selectively coupling the parity bits to ECC logic circuitry in an ECC mode.

  • Publication number: 20030160630
    Abstract: A repeater circuit for detecting and accelerating the transitioning edge of a signal on a bi-directional bus. The repeater includes rising and falling edge detectors for detecting a change in the potential level of the bi-directional bus and does not require logic for determining the direction of propagation of the signal. The edge detectors subsequently activate a drive circuit for accelerating the potential level transition of the signal on the bi-directional bus. A buffer circuit can be placed between the edge detectors and the bi-directional bus to ensure that any transition on the bi-directional bus is an intended signal transition and not a voltage spike.
