Patent number: 11955158Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for scheduling targeted refreshes in a memory device. Memory cells in a memory device may be volatile and may need to be periodically refreshed as part of an auto-refresh operation. In addition, certain rows may experience faster degradation, and may need to undergo targeted refresh operations, where a specific targeted refresh address is provided and refreshed. The rate at which targeted refresh operations need to occur may be based on the rate at which memory cells are accessed. The memory device may monitor accesses to a bank of the memory, and may use a count of the accesses to determine if an auto-refresh address or a targeted refresh address will be refreshed.Type: GrantFiled: December 12, 2022Date of Patent: April 9, 2024Inventors: Jason M. Brown, Daniel B. Penney

Patent number: 11854618Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for determining extremum numerical values. Numerical values may be stored in files of a stack, with each bit of the numerical value stored in a content addressable memory (CAM) cell of the file. Each file may be associated with an accumulator circuit, which provides an accumulator signal. An extremum search operation may be performed where a sequence of comparison bits are compared in a bit-by-bit fashion to each bit of the numerical values. The accumulator circuits each provide an accumulator signal which indicates if the numerical value in the associated file is an extremum value or not. Examples of extremum search operations include finding a maximum of the numerical values and a minimum of the numerical values.Type: GrantFiled: September 1, 2021Date of Patent: December 26, 2023Assignee: Micron Technology, Inc.Inventors: Daniel B.

Publication number: 20220328098Abstract: Memory devices may have a memory array and a delay locked loop (DLL) circuit that adjusts signals associated with operations to access of the memory array. The memory device may also include a controller that delays an access command to access the memory array by transmitting the access command through delay circuitry of the DLL circuit. This may cause the access command to be delayed by a first duration of time when output from the delay circuitry. Delay of the access command may align a data signal and the access command such that the access command and a system clock may cause latching of suitable data of the data signal.Type: ApplicationFiled: June 29, 2022Publication date: October 13, 2022Inventors: Jason M.
