Data transmission device and method, memory and storage system

The embodiment of the invention provides a data transmission device and method, a memory and a storage system. The data transmission device comprises a post-write generator, the post-write generator is configured to generate a post-write clock signal after a certain write operation period is finished, and the post-write clock signal is used for enabling residual data in data to be written to be loaded to a page buffer in a memory; wherein the to-be-written data is data expected to be loaded into the page buffer in the writing operation period; the residual data are data which are not loaded to the page buffer in the data to be written in the write operation period. 本发明实施例提供一种数据传输装置、方法、存储器及存储系统。其中，所述数据传输装置包括：后写入发生器，所述后写入发生器被配置为：在某一写入操作周期结束之后，生成后写入时钟信号，所述后写入时钟信号用于使待写入数据中的剩余数据能够被加载到存储器中的页缓存器；其中，所述待写入数据为期望在所述写入操作周期加载到所述页缓存器中的数据；所述剩余数据为在所述写入操作周期所述待写入数据中未能加载到所述页缓存器的数据。
