Memory devices with four data line bias levels
摘要:
Memory devices might include a first latch to store a first data bit; a second latch to store a second data bit; a data line selectively connected to the first latch, the second latch, and a string of series-connected memory cells; and a controller configured to bias the data line during a programing operation of a selected memory cell. The controller may with the first data bit equal to 0 and the second data bit equal to 0, bias the data line to a first voltage level; with the first data bit equal to 1 and the second data bit equal to 0, bias the data line to a second voltage level; with the first data bit equal to 0 and the second data bit equal to 1, bias the data line to a third voltage level; and with the first data bit equal to 1 and the second data bit equal to 1, bias the data line to a fourth voltage level.
