Technologies to address individual bits in memory
11593263 · 2023-02-28 · ·

Technologies for addressing individual bits in memory include a device having a memory that includes partitions that each have tiles, in which each tile stores an individual bit. The device also includes circuitry to receive a request to access (e.g., read or write) a sequence of bits in a partition. The request specifies a logical row or column address. A corresponding tile is determined from the logical row or column address and for each bit in the sequence. The corresponding tile is accessed to read or write the bit therein.

Methods for minimizing fragmentation in SSD within a storage system and devices thereof

A method, non-transitory computer readable medium, and device that assists with reducing memory fragmentation in solid state devices includes identifying an allocation area within an address range to write data from a cache. Next, the identified allocation area is determined for including previously stored data. The previously stored data is read from the identified allocation area when it is determined that the identified allocation area comprises previously stored data. Next, both the write data from the cache and the read previously stored data are written back into the identified allocation area sequentially through the address range.

Memory compression hashing mechanism

An apparatus to facilitate memory data compression is disclosed. The apparatus includes a memory and having a plurality of banks to store main data and metadata associated with the main data and a memory management unit (MMU) coupled to the plurality of banks to perform a hash function to compute indices into virtual address locations in memory for the main data and the metadata and adjust the metadata virtual address locations to store each adjusted metadata virtual address location in a bank storing the associated main data.

FLASH OPTIMIZED COLUMNAR DATA LAYOUT AND DATA ACCESS ALGORITHMS FOR BIG DATA QUERY ENGINES
20180011690 · 2018-01-11 ·

A technique relates to flash-optimized data layout of a dataset for queries. Selection columns are stored in flash memory according to a selection optimized layout, where the selection optimized layout is configured to optimize predicate matching and data skipping. The selection optimized layout, for each selection column, is formed by storing a selection column dictionary filled with unique data values in a given selection column, where the unique data values are stored in sorted order in the selection column dictionary. Row position designations are stored corresponding to each row position that the unique data values are present within the given selection column, without duplicating storage of any of the unique data values that occur more than once in the given selection column.

20180011786 · 2018-01-11 ·

The present invention relates to a dynamic memory management method which includes generating an N-dimensional memory address space in which coordinates are in a range of N natural numbers, the sum of which is the number of bits; and mapping a predetermined linear memory address region to an address region in the N-dimensional memory address space.

Input/output size control between a host system and a memory sub-system
11709632 · 2023-07-25 · ·

A memory sub-system configured to dynamically determine input/output sizes of write commands based on a media physical layout of a memory sub-system. The memory sub-system can identify, dynamically in response to write commands being selected for execution in media units of the memory sub-system, a portion of a media layout that maps from logical addresses identified by the write commands in the logical address space to physical addresses of memory units in the media units. Based on the media layout, an input/output size for a next write command is identified and transmitted to the host system in a response. The host system generates the next write command and configures the amount of data to be written through the next write command based on based on the input/output size identified in the response.
