INTER-ROW DATA TRANSFER IN MEMORY DEVICES

摘要

A method and apparatus for inter-row data transfer in memory devices is described. Data transfer from one physical location in a memory device to another is achieved without engaging the external input/output pins on the memory device. In an example method, a memory device is responsive to a row transfer (RT) command which includes a source row identifier and a target row identifier. The memory device activates a source row and storing source row data in a row buffer, latches the target row identifier into the memory device, activates a word line of a target row to prepare for a write operation, and stores the source row data from the row buffer into the target row.

1. A method for inter-row data transfer in a memory device, comprising:
responsive to a row transfer (RT) command including a source row identifier and a target row identifier,
activating a source row corresponding to the source row identifier and storing source row data in a row buffer;latching the target row identifier into the memory device;activating a word line of a target row corresponding to the target row identifier to prepare for a write operation; andstoring the source row data from the row buffer into the target row.
