  • Patent number: 11935601
    Abstract: Memories, memory controllers, and computing systems and their methods of operation are disclosed. In some embodiments, a method of accessing a memory includes accessing a first bit line corresponding to a sense amplifier and accessing a second bit line corresponding to the sense amplifier. In some embodiments, a memory controller includes a second memory configured to store data of a second data type. In some embodiments, a method includes operating a memory in a second mode in response to receiving an input to change the operation of the memory from a first mode to the second mode.

  • Publication number: 20240054050
    Abstract: Error correcting memory systems and methods of operating the memory systems are disclosed. In some embodiments, a memory system includes: a data memory; an ECC memory; and a data scrubbing circuit electrically coupled to the ECC memory and the data memory. The data scrubbing circuit may be configured to, in response to receiving a scrub data command, correct an error in the data memory. A code word length used to correct the error may be longer than a word length used during normal access of the data memory. In some embodiments, a memory system includes a first memory circuit associated with a first bit error rate and a second memory circuit associated with a second bit error rate. In some embodiments, a memory system includes an error correctable multi-level cell (MLC) array.
