    摘要: The circuit provides one or several banks of capacitors, the capacitors in each bank being identical in size. A single fuse for each bank of capacitors controls the connection of the capacitors to a pulse-width-determining node on each of the ATD (address-transition-detect) pulse generators of the SRAM device. Depending on the position of the fuse in the circuit, the blowing of a single fuse can either add to the capacitance at the ATD nodes or substract from it. Thus the pulse-width of all ATD pulse generators can be adjusted shorter or longer simultaneously by blowing a single fuse only.

    摘要: A system and method for effectively implementing a high-speed DRAM device may include memory cells that each have a bitline for transferring storage data, a wordline for enabling an accelerated-write operation in the memory cell, and a data storage node with a corresponding cell voltage. An accelerated-write circuit may then directly provide the storage data to an appropriate bitline in a pre-toggled state in response to one or more accelerated-write enable signals. The corresponding cell voltage may therefore begin a state-change transition towards the pre-toggled state immediately after the wordline is activated to successfully reach a full-state level before the wordline is deactivated during a high-speed memory cycle.
