  • Publication number: 20160005458
    Abstract: A sectioned bit line of an SRAM memory device, an SRAM memory device having a sectioned bit line, and associated systems and methods are described, including embodiments having sectioned bit lines with hierarchical aspects. In one illustrative implementation, each sectioned bit line may comprise a local bit line, a memory cell connected to the local bit line, and a pass gate coupled to the local bit line, wherein the pass gate is configured to be coupled to a global bit line. Further, in some embodiments, the sectioned bit lines are arranged in hierarchical arrays. In other implementations, SRAM memory devices may be configured involving sectioned bit lines (including hierarchical) and a global bit line wherein the pass gates are configured to connect and isolate the sectioned bit line and the global bit line.

  • Patent number: 6762973
    Abstract: The present invention provides data coherent logic for an SRAM device. The present invention utilizes a data strobe signal and an output strobe signal to control data written into and read out of the. SRAM device from an input/output pad. Data coherent logic is designed to resolve timing conflicts between the data and output strobe signals. The logic selectively delays the output strobe signal when a match occurs for data requested in a read operation immediately following a write operation. The delay allows sufficient time for the data to be registered and selected before being outputted from the device.

  • Patent number: 5355343
    Abstract: A static memory array incorporates a bit line equalization transistor which is normally conductive so that the quiescent condition of the bit lines is to remain equalized. The equalization transistor is cut off for a predetermined period in response to detection of address transition. When a subsequent address transition occurs before the expiration of a predetermined period, the equalization transistor conducts again briefly, which conduction is followed by a period of nonconduction, for a predetermined duration, as long as another address transition is not detected. The equalization technique is applicable to local data lines as well as the bit lines of the memory.
