Embodiment Construction

[0090] The present invention is described below based on examples, but the present invention is not limited to these examples. In the following detailed description of the invention, some specific details are set forth in detail. The present invention can be fully understood by those skilled in the art without the description of these detailed parts. In order to avoid obscuring the essence of the present invention, well-known methods, procedures, and flow charts are not described in detail. Additionally, the drawings are not necessarily drawn to scale.

[0091] In the data writing method of the prior art, after a write verification fails, multiple write operations are performed on all the verified storage units in batches, and the multiple write operations have no difference in the number of operated storage units. In this data writing method, the number of writing operations is relatively large, and each data writing will take a lot of time, resulting in low data writing ef...

Abstract

The embodiment of the invention provides a data writing method and system. The method comprises the steps of obtaining the maximum quantity of storage units which can be successfully written through one-time writing operation; obtaining a verification result of the current write verification after the current write verification of the plurality of storage units fails; grouping the plurality of storage units according to the verification result, so that the number of the storage units which fail to write in each unit group is not greater than the maximum number; and performing multiple times ofwriting operations on the plurality of storage units in batches according to the unit groups. The technical problem that in the prior art, the data writing efficiency of a memory is low is solved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a data writing method and a writing system applied to a memory. Background technique [0002] Memory is a device used to store information in modern information technology, and the speed of reading and writing data is crucial to memory. When the memory is writing data, it needs to go through two operations: write verification (program veriyf) and write operation (program). Among them, the write verification is used to read the data written in the storage unit after the write operation to judge Whether the storage unit writes data successfully. [0003] figure 1 Shown is a flow chart of a data writing method applied to a memory in the prior art. refer to figure 1 , the data writing method in the prior art is usually: one write verification → multiple write operations after the write verification fails → one write verification → ..., and the cycle continues until the wri...
