  • Publication number: 20240079053
    Abstract: In one embodiment, a static random access memory (SRAM) device is provided. The SRAM device includes a memory cell, a bit line couple to the memory cell, a voltage supply line coupled to the memory cell, a control circuitry. The control circuitry is configured to charge a voltage supply line while the voltage supply line is electrically isolated from a bit line. A portion of the charge is transferred from the voltage supply line to the bit line. The voltage supply line is recharged while the voltage supply line is electrically isolated from the bit line storing the transferred portion of the charge. The memory cell is accessed using the recharge on the voltage supply line.

  • Patent number: 11164764
    Abstract: The current disclosure describes carrier tape systems that include a carrier tape substrate and a cover tape. The carrier tape system includes a plurality of repetitive adhesion areas where the carrier tape substrate and cover tape are attached to each other and non-adhesion areas where the carrier tape substrate and cover tape are not attached to each other. Separating the cover tape and the carrier tape substrate at these repetitive adhesion and non-adhesion areas imparts a vibration to the cover tape which impedes or prevents semiconductor devices carried in pockets of the carrier tape substrate from adhering to adhesive on the cover tape.
