Publication number: 20220044965Abstract: A method used in forming a conductive via of integrated circuitry comprises forming a lining laterally over sidewalk of an elevationally-elongated opening. The lining comprises elemental-form silicon. The elemental-form silicon of an uppermost portion of the lining is ion implanted in the elevationally-elongated opening. The ion-implanted elemental-form silicon of the uppermost portion of the lining is etched selectively relative to the elemental-form silicon of a lower portion of the lining below the uppermost portion that was not subjected to said ion implanting. The elemental-form silicon of the lower portion of the lining is reacted with a metal halide to form elemental-form metal in a lower portion of the elevationally-elongated opening that is the metal from the metal halide. Conductive material in the elevationally-elongated opening is formed atop and directly against the elemental-form metal. Other embodiments, including structure independent of method, are disclosed.Type: ApplicationFiled: August 7, 2020Publication date: February 10, 2022Applicant: Micron Technology, Inc.Inventors: Yiping Wang, Jordan D.

Patent number: 11244713Abstract: Methods, systems, and devices for operating a memory array with variable page sizes are described. The page size may be dynamically changed, and multiple rows of the memory array may be accessed in parallel to create the desired page size. A memory bank of the array may contain multiple memory sections, and each memory section may have its own set of sense components (e.g., sense amplifiers) to read or program the memory cells. Multiple memory sections may thus be accessed in parallel to create a memory page from multiple rows of memory cells. The addressing scheme may be modified based on the page size. The logic row address may identify the memory sections to be accessed in parallel. The memory sections may also be linked and accessing a row in one section may automatically access a row in a second memory section.Type: GrantFiled: January 21, 2020Date of Patent: February 8, 2022Assignee: Micron Technology, Inc.Inventor: Corrado Villa

Patent number: 11244729Abstract: A memory device to search for a voltage optimized to read a group of memory cells. In response to a read command, the memory device measures first signal and noise characteristics of the memory cells by reading the memory cells at first test voltages. Based on the first signal and noise characteristics, the memory device may determine that the optimized read voltage is outside of a range of the first test voltages. In response, the memory device determines, based on the first signal and noise characteristics, an estimate of the optimized read voltage, and measures second signal and noise characteristics by reading at second test voltages configured around the estimate. The optimized read voltage can be computed based at least in part on the second signal and noise characteristics. The memory device retrieves data from the memory cells using the optimized read voltage.Type: GrantFiled: August 7, 2020Date of Patent: February 8, 2022Assignee: Micron Technology, Inc.Inventors: Patrick Robert Khayat, James Fitzpatrick, AbdelHakim S.

Patent number: 11243804Abstract: Systems, apparatuses, and methods to implement time to live for memory access by processors. For example, a processor has a register configured to store a parameter specifying a time duration indicative of the desired time to live. A memory system has multiple components with different latencies for memory access. When the memory controller of the processor sends a command to the memory system to load an item from a memory address, the memory system can fail to provide, to the processor within the time duration, the item from the memory address currently being hosted in a first component. In response, the memory controller can send a signal to abort the command; and the memory system can select a second component having a memory access latency shorter than the first component, and change the hosting of the memory address from in the first component to in the second component.Type: GrantFiled: November 19, 2019Date of Patent: February 8, 2022Assignee: Micron Technology, Inc.Inventor: Justin M.

Patent number: 11244715Abstract: Memory cells are described that include two reference voltages that may store and sense three distinct memory states by compensating for undesired intrinsic charges affecting a memory cell. Although embodiments described herein refer to three memory states, it should be appreciated that in other embodiments, the memory cell may store or sense more than three charge distributions using the described methods and techniques. In a first memory state, a programming voltage or a sensed voltage may be higher than a first reference voltage and a second reference voltage. In a second memory state, the applied voltage or the sensed voltage may be between the first and the second reference voltages. In a third memory state, the applied voltage or the sensed voltage may be lower than the first and the second reference voltages. As such, the memory cell may store and retrieve three memory states.Type: GrantFiled: December 1, 2020Date of Patent: February 8, 2022Assignee: Micron Technology, Inc.Inventor: Daniele Vimercati
