  • Patent number: 9812189
    Abstract: An apparatus is provided which comprises: a memory array; first logic to detect whether first and second word-lines (WL) for a row of the memory array are active; and second logic to deactivate one of the first and second WLs such that one of the first and second WLs is active for the row.

  • Patent number: 9607687
    Abstract: In one embodiment, a memory cell circuit for storing data includes a pair of cross-coupled inverters for storing states of the memory cell circuit. Access devices provide access to the pair of cross-coupled inverters. The memory cell circuit also includes a set of electrically inactive p-type metal oxide semiconductor (PMOS) devices that are coupled to the pair of cross-coupled inverters. The set of electrically inactive PMOS devices in combination with a portion (e.g., PMOS devices) of the pair of cross-coupled inverters enables a continuous p-type diffusion layer for the memory cell circuit.

  • Patent number: 8982659
    Abstract: Techniques are disclosed that allow for power conservation in integrated circuit memories, such as SRAM. The techniques can be embodied in circuitry that allows for floating of bitlines to eliminate or otherwise reduce power leakage associated with precharging bitlines. For instance, the techniques can be embodied in a bitline floating circuit having a single logic gate for qualifying the precharge control signal with a wake signal, so that precharging of the bitline does not occur if the wake signal is not in an active state. The techniques further allow for the elimination or reduction of unnecessary power consumption by the I/O circuitry or the memory array, such as when the memory array is not being accessed or when the array or a portion thereof is permanently disabled for yield recovery.

  • Patent number: 8868836
    Abstract: Methods and apparatus to reduce minimum operating voltage through a hybrid cache design are described. In one embodiment, a cache with different size bit cells may be used, e.g., to reduce minimum operating voltage of an integrated circuit device that includes the cache and possibly other logic (such as a processor). Other embodiments are also described.

  • Publication number: 20110161783
    Abstract: An apparatus and method is described herein directly matching coded tags. An incoming tag address is encoded with error correction codes (ECCs) to obtain a coded, incoming tag. The coded, incoming tag is directly compared to a stored, coded tag; this comparison result, in one example, yields an m-bit difference between the coded, incoming tag and the stored, coded tag. ECC, in one described embodiment, is able to correct k-bits and detect k+1 bits. As a result, if the m-bit difference is within 2k+2 bits, then valid codes—coded tags—are detected. As an example, if the m-bit difference is less than a hit threshold, such as k-bits, then a hit is determined, while if the m-bit difference is greater than a miss threshold, such as k+1 bits, then a miss is determined.
