Patent number: 11942151Abstract: A variety of applications can include one or more memory devices having one or more memory arrays of memory cells, where each memory cell is a resistive memory cell arranged such that a clamp current for the memory cell can be provided by an access line biasing circuit to the memory cell opposite a coupling of a sense circuit to a digit line to the memory array. The access line biasing circuit and the sense circuit can be operated in a digit line precharge phase and an access line biasing phase of a memory cell of the memory array using a set of switches to control activities for the memory cell in the memory array, the sense circuit, and the access line biasing circuit. A reference current can be provided from the access line biasing circuit to the sense circuit. Additional devices, systems, and methods are discussed.Type: GrantFiled: April 14, 2022Date of Patent: March 26, 2024Assignee: Micron Technology, Inc.Inventors: Ferdinando Bedeschi, Pierguido Garofalo, Umberto Di Vincenzo, Claudia Palattella

Patent number: 11942958Abstract: A method has been disclosed that relates to electrical variability compensation technique for configurable-output circuits. The compensation technique can be applied to a generality of circuits whose output has to vary between two electrical limits spanning the range in between them according to a specific code given as input. A switching sequence that is process gradient-direction agnostic has been disclosed which limits variability. An electric device comprising a processing gradient-direction agnostic configurable-output circuit has been also disclosed.Type: GrantFiled: June 22, 2022Date of Patent: March 26, 2024Assignee: Micron Technology, Inc.Inventor: Pierguido Garofalo

Patent number: 11854647Abstract: A level shifter receives an input signal in a first power domain and generates a corresponding output signal in a second power domain. The transition time of the output signal may be longer during a low-to-high transition than during a high-to-low transition or vice versa. The level shifter may provide two outputs, wherein one of the two outputs has a shorter transition time during a high-to-low transition and the other output has a shorter transition time during a low-to-high transition. By using an inverter on the second output, two non-inverted outputs are generated with different transition times. A ramp selection circuit is used to select between the first output and the inverted second output. The ramp selection circuit selects the output with the shortest transition time.Type: GrantFiled: July 29, 2021Date of Patent: December 26, 2023Assignee: Micron Technology, Inc.Inventor: Pierguido Garofalo
