Integrated circuit device

TL;DR: In this paper, an integrated circuit (IC) is defined as a memory array with plural bit lines coupled with corresponding columns of memory cells in the array, plural reference lines, a plurality of access gate word lines coupled to access gates in corresponding rows in an array, and a memory gate word line coupled to memory gates in respective rows in corresponding arrays.

Abstract: An integrated circuit device, based on this architecture comprises a memory array with plural bit lines coupled with corresponding columns of memory cells in the array, plural reference lines, a plurality of access gate word lines coupled to access gates in corresponding rows in the array and a plurality of memory gate word lines coupled to memory gates in corresponding rows in the array. The memory cells in the array include respective access transistors having access gates and memory transistors having memory gates arranged in series between the corresponding bit lines and one of the plural reference lines. A memory transistor in a memory cell comprises a semiconductor body including a channel having a channel surface and a charge storing dielectric stack between the memory gate and the channel surface. The dielectric lamination layer comprises a tunneling dielectric layer connected with one of the memory gate and the channel surface and a blocking dielectric layer, and the dielectric lamination layer also comprises an electric charge trapping dielectric layer arrange on the tunneling dielectric layer.
