Abstract: A memory device includes a memory array including a first memory plane and a second memory plane, and a peripheral circuit coupled to the memory array and configured to perform an operation. The operation includes receiving a first instruction and input data, and in response to the first instruction, writing first data of the input data to the first memory plane and second data of the input data to the second memory plane. The second data is configured to indicate whether the first data has been performed with an inversion operation prior to transmission.

Abstract: A computer-implemented method for partition table data writing includes obtaining a first data row to be written into a first partition table and a current partitioning rule indicating at least that the first partition table includes a partitioning key that is a basis for dividing data rows to be written into logical partitions and a first quantity of partitions. A target logical partition corresponding to the first data row is determined. A target physical partition is determined, where the target physical partition has a globally unique partition identifier. The globally unique partition identifier of the target physical partition and an auto-increment identifier of the first data row to the first data row are added as a composite primary key value. The first data row with the composite primary key value is stored to the first partition table.

Abstract: The present disclosure provides a foldable ironing board. The foldable ironing board includes a panel, a support foot, and a sliding support member. The panel includes a first panel and a second panel in a mutually movable connection. The support foot includes a first support foot and a second support foot arranged opposite each other; wherein the first support foot extends along a length direction of a bottom of the first panel, and the second support foot extends along a length direction of a bottom of the second panel. An end of the first support foot and an end of the second support foot, that are opposite to each other, are in a mutually movable connection through the sliding support member. The sliding support member is capable of sliding reciprocally along an extension direction of the first support foot and the second support foot.
