Abstract: A memory system includes a memory device comprising a content addressable memory (CAM) block comprising a plurality of key tables each storing a respective plurality of stored search keys. The memory system further includes a processing device that receives, from a requestor, an input search key and an indication of one of the plurality of key tables and identifies a match between the input search key and one of the plurality of stored search keys in the one of the plurality of key tables. The one of the plurality of stored search keys has an associated offset value indicating a location in a sorted string table (SSTable) corresponding to the one of the plurality of key tables. The processing device further reads the offset value from the one of the plurality of key tables and returns, to the requestor, the offset value read from the one of the plurality of key tables. The requestor can retrieve, from the location in the SSTable, data representing a value associated with the input search key.

Abstract: A search pattern is generated based on an input search word comprising a first sequence of bits. The search pattern comprises a first set of signals representing the input search word and a second set of signals representing a second sequence of bits comprising an inverse of the first sequence of bits. The search pattern is provided as input to search lines of a content addressable memory (CAM) block. The search pattern causes at least one string in the CAM block to be conductive and provide a signal to a page buffer connected to the string in response to the input search word matching a data entry stored on the string. A location of the data entry is determined based on data read from the page buffer and the location is output.

Abstract: A search pattern is generated based on an input search word comprising a first sequence of bits. The search pattern comprises a representation of the input search word and a representation of an inverse of the input search word. The search pattern is provided as input to search lines of a ternary content-addressable memory (TCAM) block. A subset of the search lines is set to a logical high state based on a first portion of the input search word being designated as don't-care bits. The search pattern causes at least one string in the CAM block to be conductive and provide a signal in response to a data entry stored on the string comprising a second portion of the input search word that excludes the don't-care bits. A location of the data entry is determined and output.

Abstract: An access request is received. The access request comprises a physical page address corresponding to a primary memory block of a memory device, an input security key, and a logical page address corresponding to the physical page address. The input security key is provided as input to a (CAM) block that stores a plurality of security keys to verify that the input security key matches a stored security key. A location of the stored security key is checked to verify that it corresponds to the logical page address included in the access request based a predetermined mapping. Based on verifying that the stored security key corresponds to the logical page address included in the access request, the physical page address corresponding to the primary memory block is accessed.

Abstract: A memory system includes a memory device comprising a programming buffer and a content addressable memory (CAM) block. The memory system further includes a processing device that receives a plurality of data entries to be stored at the memory device and stores the plurality of data entries in a plurality of pages of the programming buffer, each of the plurality of pages of the programming buffer comprising a respective subset of the plurality of data entries. The processing device further initiates a conversion operation to copy the plurality of data entries from the programming buffer to the CAM block. The conversion operation includes reading respective portions of each data entry in each respective subset of the plurality of data entries from the plurality of pages of the programming buffer, and writing the respective portions to respective CAM pages of the CAM block.

Abstract: A memory system includes a memory device comprising a content addressable memory (CAM) block storing a plurality of stored search keys. The memory system further includes a processing device that receives an input search key and identifies, from the plurality of stored search keys in the CAM block, multiple redundant copies of a stored search key that match the input search key. The processing device further determining whether a number of the multiple redundant copies of the stored search key that match the input search key satisfies a threshold criterion. Responsive to the number of the multiple redundant copies of the stored search key that match the input search key satisfying the threshold criterion, the processing device determines a match result for the input search key.

The memory device further includes control logic that determines a first number of memory cells in at least one string of the CAM block storing one of the plurality of stored search keys, the first number of memory cells storing a first logical value, and stores a calculated parity value representing the first number of memory cells in a page cache associated with the CAM block. The control logic further reads stored parity data from one or more memory cells in the at least one string, the one or more memory cells connected to one or more additional wordlines in the CAM block, and compares the calculated parity value to the stored parity data to determine whether an error is present in the one of the plurality of stored search keys in the CAM block.
