Kioxia Corporation patent applications published on October 5th, 2023
Summary of the patent applications from Kioxia Corporation on October 5th, 2023
Kioxia Corporation has recently filed several patents related to semiconductor storage devices and memory systems. These patents involve various aspects such as the structure of the storage devices, memory cell arrays, control circuits, and lithography processes. Some notable applications of these patents include:
- A semiconductor storage device consisting of multiple layers of conductive material on a substrate, with a pillar containing a semiconductor layer. The pillar intersects with the conductive layers to act as memory cells.
- A semiconductor memory device with stacked layers, including a gate electrode layer, insulating layers, and a semiconductor layer. A specific layer contains silicon and nitrogen, with different regions having varying concentrations of fluorine.
- A memory system with a semiconductor memory and a controller. The controller instructs the semiconductor memory to perform operations on selected blocks, applying voltage to memory cells. The number of blocks to which voltage is applied per unit time is greater in the second operation compared to the first operation.
- A circuit for calculating syndromes in a composite field, using matrix product calculations and arithmetic matrices.
- A semiconductor storage device consisting of two chips bonded together, with conductive layers, a semiconductor pillar, and power supply electrodes on the first chip, and a semiconductor substrate and transistors on the second chip.
- A semiconductor device with a substrate, transistor, insulating layer, and a sealing portion. The sealing portion encircles the outer periphery of a region within the substrate and contains a void.
- A plate for imprint lithography, with a patterned portion having a recessed groove and a columnar portion extending beyond the surface.
- A semiconductor memory device with a memory cell array, word line, bit lines, sense amplifier, and controller. It performs write operations using multiple program loops, applying different voltages to bit lines and a program voltage to the word line.
- A semiconductor storage device with multiple strings of memory cell transistors, word lines, bit lines, a source line, and a control circuit. The control circuit performs erase operations on the memory cell transistors using different erase-verify operations for open and closed blocks.
- A semiconductor memory device with a first pad for connection, a clock generation circuit, an output circuit, a designation circuit for selecting time slots, and a peak control circuit for generating a current peak at a specific timing.
Overall, Kioxia Corporation has been actively filing patents related to various aspects of semiconductor storage devices and memory systems, showcasing their commitment to innovation in the field.
