Publication number: US20210027850A1
Application number: 17/066,663

A methodology and structure for performing an erase verify in non-volatile memory is described. Both the odd wordlines and the even wordlines are driven to a high voltage level. This can be done simultaneously. The simultaneous charging of both the odd wordlines and the even wordlines, even when the erase verify will occur on only one of the odd or even wordlines reduces RC delay in the charging of the wordlines. After the odd and even wordlines are charged, then one set of wordlines, either the odd or even wordlines, is dropped to the erase verify voltage. The erase sense operation is then performed.

A data storage system includes a storage controller and a storage medium in communication with the storage controller. The storage medium includes a memory core comprising an array of memory cells and core control logic configured to perform operations on memory cells in the array in accordance with instructions received from the storage controller. The core control logic comprises a firmware-implemented condition evaluation machine configured to determine whether a plurality of memory core conditions are met. The core control logic also comprises a firmware-implemented signal setting machine configured to set or reset a plurality of respective memory operation signals to implement the operations on the memory cells based on respective condition evaluation machine determinations.

Application number: 16/682,183

A data storage system includes a memory including a plurality of memory cells; and control logic configured to receive a first data string and determine a data type of the first data string. If the first data string is a combination command, the control logic obtains a plurality of sub-commands based on the first data string. Meanwhile, the control logic receives a second data string, determines that it represents an address, and decodes the address. While decoding the address or otherwise processing the second data string, the control logic performs a system operation specified by one of the sub-commands. The control logic also performs a memory operation, specified by another of the sub-commands, on one or more of the plurality of memory cells in accordance with the decoded address.
