Patent number: 11966289Abstract: Systems and methods are disclosed including a memory device and a processing device operatively coupled to the memory device. The processing device can perform operations comprising performing a first read operation on the memory device to retrieve first data; determining, from the first data, second data indicative of a write temperature associated with the first data, wherein the write temperature is indicative of a temperature measured during a write operation; determining a read voltage value based on the second data; and performing a second read operation on the memory device using the read voltage value to obtain the first data.Type: GrantFiled: June 2, 2022Date of Patent: April 23, 2024Assignee: Micron Technology, Inc.Inventors: Andrea Giovanni Xotta, Umberto Siciliani

Publication number: 20240071427Abstract: Control logic in a memory device receives, from a requestor, a request to read data from the memory array, the request comprising an indication of a segment of the memory array where the data is stored and performs, using previously configured read operation parameters, a first read operation to read the data and a write temperature associated with the data from the memory array. The control logic determines whether the previously configured read operation parameters satisfy a temperature criterion and responsive to determining that the previously configured read operation parameters do not satisfy the temperature criterion, configures the memory device with updated read operation parameters, and performs, using the updated read operation parameters, a second read operation to read the data from the memory array.Type: ApplicationFiled: August 24, 2023Publication date: February 29, 2024Inventors: Andrea Giovanni Xotta, Umberto Siciliani, Tommaso Vali

Patent number: 11842078Abstract: A memory device includes a memory array configured with a plurality of memory planes, and control logic, operatively coupled with the memory array. The control logic performs a plurality of asynchronous memory access operations on the plurality of memory planes, detects an occurrence of an asynchronous interrupt event, and initiates a termination procedure for each of the plurality of asynchronous memory access operations to permit each of the plurality of asynchronous memory access operations to end at different times. In response to a first memory access operation of the plurality of asynchronous memory access operations ending, the control logic asserts a command result signal, wherein the command result signal is de-asserted automatically in response to receipt of a subsequent memory access command directed to any of the plurality of memory planes, and asserts a persistent event register signal, wherein the command result signal is de-asserted in response to receipt of a clear event register command.Type: GrantFiled: January 31, 2022Date of Patent: December 12, 2023Assignee: Micron Technology, Inc.Inventors: Andrea Giovanni Xotta, Guido Luciano Rizzo, Umberto Siciliani, Tommaso Vali, Luca De Santis, Walter Di Francesco

Publication number: 20230017305Abstract: A variety of applications can include apparatus or methods that provide a well ring for resistive ground power domain segregation. The well ring can be implemented as a n-well in a p-type substrate. Resistive separation between ground domains can be generated by biasing a n-well ring to an external supply voltage. This approach can provide a procedure, from a process standpoint, that provides relatively high flexibility to design for chip floor planning and simulation, while providing sufficient noise rejection between independent ground power domains when correctly sized. Significant noise rejection between ground power domains can be attained.Type: ApplicationFiled: April 27, 2022Publication date: January 19, 2023Inventors: Mattia Cichocki, Vladimir Mikhalev, Phani Bharadwaj Vanguri, James Eric Davis, Kenneth William Marr, Chiara Cerafogli, Michael James Irwin, Domenico Tuzi, Umberto Siciliani, Alessandro Alilla, Andrea Giovanni Xotta, Chung-Ping Wu, Luigi Marchese, Pasquale Conenna, Joonwoo Nam, Ishani Bhatt, Fulvio Rori, Andrea D'Alessandro, Michele Piccardi, Aleksey Prozapas, Luigi Pilolli, Violante Moschiano
