Patent number: 11392494Abstract: Technologies for column reads for clustered data include a device having a column-addressable memory and circuitry connected to the memory. The column-addressable memory includes multiple dies. The circuitry may be configured to determine multiple die offsets based on a logical column number of the data cluster, determine a base address based on the logical column number, program the dies with the die offsets. The circuitry is further to read logical column data from the column-addressable memory. To read the data, each die adds the corresponding die offset to the base address. The column-addressable memory may include multiple command/address buses. The circuitry may determine a starting address for each of multiple logical columns and issue a column read for each starting address via a corresponding command/address bus. Other embodiments are described and claimed.Type: GrantFiled: June 5, 2020Date of Patent: July 19, 2022Assignee: Intel CorporationInventors: Jawad Khan, Chetan Chauhan, Rajesh Sundaram, Sourabh Dongaonkar, Sandeep Guliani, Dipanjan Sengupta, Mariano Tepper

Patent number: 11327881Abstract: Technologies for media management for providing column data layouts for clustered data include a device having a column-addressable memory and circuitry connected to the memory. The circuitry is configured to store a data cluster of a logical matrix in the column-addressable memory with a column-based format and to read a logical column of the data cluster from the column-addressable memory with a column read operation. Reading the logical column may include reading logical column data diagonally from the column-address memory, including reading from the data cluster and a duplicate copy of the data cluster. Reading the logical column may include reading from multiple complementary logical columns. Reading the logical column may include reading logical column data diagonally with a modulo counter. The column data may bread from a partition of the column-address memory selected based on the logical column number. Other embodiments are described and claimed.Type: GrantFiled: May 13, 2020Date of Patent: May 10, 2022Assignee: Intel CorporationInventors: Chetan Chauhan, Sourabh Dongaonkar, Rajesh Sundaram, Jawad Khan, Sandeep Guliani, Dipanjan Sengupta, Mariano Tepper

Patent number: 10902909Abstract: Apparatuses and methods for accessing a memory cell are described. An example apparatus includes a first voltage circuit coupled to a node and is configured to provide a first voltage to the node and includes a second voltage circuit coupled to a node and is configured to provide a second voltage to the node. A memory cell is coupled to first and second access lines. A decoder circuit is coupled to the node and the first access line, and is configured to selectively couple the first access line to the node. The first voltage circuit is configured to provide the first voltage to the node before the second voltage circuit provides the second voltage to the node, and the second voltage circuit stops providing the second voltage before the node reaches the second voltage.Type: GrantFiled: July 25, 2018Date of Patent: January 26, 2021Assignee: Micron Technology, Inc.Inventors: Sandeep Guliani, Balaji Srinivasan
