  • FLY-OVER CONDUCTOR SEGMENTS IN INTEGRATED CIRCUITS WITH SUCCESSIVE LOAD DEVICES ALONG A SIGNAL PATH
    Publication number: 20130051128
    Abstract: The propagation delay of a signal through multiple load devices coupled sequentially along a conductor is improved by separating a subset of the load devices that is more distant from the signal source, and coupling the more distant subset to the signal through a fly-over conductor that bypasses the subset that is nearer to the signal source. The technique is applicable to subsets of bit cells in a random access memory (SRAM) coupled to a given word line, or to word line decoder gates coupled sequentially to a strobe signal, as well as other circuits wherein load devices selectable as a group can be divided into subsets by proximity to the signal source. In an SRAM layout with multiple levels, different metal deposition layers carry the conductor legs between the load devices versus the fly-over conductor bypassing the nearer subset.

  • SRAM READ and WRITE Assist Apparatus
    Publication number: 20120307574
    Abstract: A SRAM READ and WRITE assist apparatus comprises a bit line voltage tracking block, a READ assist timer, a READ assist unit, a WRITE assist unit a WRITE control unit. The bit line voltage tracking block detects a voltage on a tracking bit line coupled to a plurality of tracking memory cells. In response to the voltage drop on the tracking bit line, the READ assist timer generates a READ assist pulse. When the READ assist pulse has a logic high state, an activated word line is pulled down to a lower voltage. Such a lower voltage helps to improve the robustness of SRAM memory circuits so as to avoid READ and WRITE failures.

Furthermore, the timer unit controls the period in which a lower voltage from the output of the voltage divider is applied to the memory cell. Moreover, external level and timing programmable signals can be used to further adjust the voltage divider's ratio and the pulse width from the timer unit. By employing the SRAM write assist apparatus, a memory chip can perform a reliable and fast write operation.
