MEMORY DEVICES HAVING SOURCE LINES DIRECTLY COUPLED TO BODY REGIONS AND METHODS

摘要

Memory devices, memory cell strings and methods of operating memory devices are shown. Configurations described include directly coupling an elongated body region to a source line. Configurations and methods shown should provide a reliable bias to a body region for memory operations such as erasing.

主权项

1. A memory device, comprising:
a data line; a source; a first string of memory cells coupled at a first end to the data line by a first select gate, and directly coupled at a second end to the source through a second select gate; a second string of memory cells coupled at a first end to the data line by a third select gate, and directly coupled at a second end to the source through a fourth select gate; and a controller, wherein the controller is configured to concurrently bias the data line and the source to substantially the same potential, and perform a program operation on a selected memory cell of the first string of memory cells.
