Abstract
An integrated circuit structure includes an electrically erasable programmable read-only memory (EEPROM) array, which includes EEPROM cells arranged as rows and columns; a plurality of word-lines and a plurality of drain-lines extending in a column direction, and a plurality of source-lines extending in a row direction. Each of the plurality of word-lines is connected to control gates of the EEPROM cells in a same column. Each of the plurality of drain-lines is connected to drains of the EEPROM cells in a same column, wherein none of the plurality of drain-lines are shared by neighboring columns of the EEPROM cells. Each of the plurality of source-lines is connected to sources of the EEPROM cells in a same row.
