  • Patent number: 11848071
    Abstract: Disclosed are systems and methods involving memory-side write training to improve data valid window. In one implementation, a method for performing memory-side write training may comprise delaying a rising edge or a falling edge of a first data signal, delaying a rising edge or a falling edge of a second data signal, and aligning the two adjusted signals to reduce a window of time that the data signals are not valid and thereby improve or optimize the data valid window (DVW) of a memory array. According to implementations herein, various edges of data signals and clock signals may be adjusted or delayed via dedicated trim cells or circuitry present in the data paths located on the memory side of a system.

  • Patent number: 11528015
    Abstract: Disclosed are level shifters and methods of performing level shifting. In one embodiment, a level shifter is disclosed comprising an input, cross-coupled/latch circuitry, a first reference node, a second reference node, and output circuitry coupled between the cross-coupled/latch circuitry and an output, wherein the output circuitry sets the output signal to high based on rising edge of a second reference node and sets the output signal to low based on the rising edge of the first reference node. Further, in some implementations, the first reference node and the second reference node may have signals that are inverse to each other.
