Patent number: 12001340Abstract: Methods, systems, and devices for full multi-plane operation enablement are described. A flash controller can determine that a first plane of a set of planes of a memory die is an invalid plane. The flash controller can issue a single descriptor associated with a multi-plane operation for the set of planes of the memory die. The single descriptor can include a plurality of commands for the multi-plane operation in which the first command of the plurality of commands can be a duplicate of a second command of the plurality of commands based on the first plane being the invalid plane. In some cases, a negative-and (NAND) controller can receive the single descriptor associated with the multi-plane operation for the set of planes of a memory die. The NAND controller can issue a plurality of commands for the multi-plane operation based on receiving the single descriptor.Type: GrantFiled: March 21, 2023Date of Patent: June 4, 2024Assignee: Micron Technology, Inc.Inventors: Jiangang Wu, Qisong Lin, Jung Sheng Hoei, Yunqiu Wan, Ashutosh Malshe, Peng-Cheng Chen

Patent number: 7369447Abstract: A non-volatile memory is described that utilizes a cache read mode of operation, where a next page of memory is being read/sensed from the memory array by the sense amplifiers while a previously read page of memory is being read from the memory I/O buffer, wherein the next page is user selected. This random cache read mode allows for a memory with a random page read capability, in which the address of the next page of data to be read is user selectable, which benefits from the low latency of a cache read mode of operation due to concurrent data sensing and data I/O.Type: GrantFiled: September 5, 2006Date of Patent: May 6, 2008Assignee: Micron Technology, Inc.Inventors: Benjamin Louie, Yunqiu Wan, Aaron Yip, Jin-Man Han
