摘要： A non-volatile SRAM memory cell and a non-volatile semiconductor memory device capable of programming SRAM data in a SRAM (15) to a non-volatile memory unit (16) through fast operation of the SRAM (15) are disclosed. A non-volatile semiconductor memory device (1) can achieve reduction in a voltage necessary for a programming operation to program SRAM data to the non-volatile memory unit (16). Thus, a first access transistor (21 a), a second access transistor (21 b), a first load transistor (22a), a second load transistor (22b), a first drive transistor (23a), and a second drive transistor (23b) included in the SRAM (15) connected with the non-volatile memory unit (16) can each include a gate insulating film having a thickness less than or equal to 4 nm, which achieves fast operation of the SRAM (15) at a lower power supply voltage.

摘要： A voltage applied to a bit line (BL1) or a voltage applied to a source line (SL) is reduced to a value that allows a first select gate structure (5) or a second select gate structure (6) to block electrical connection between the bit line (BL1) and a channel layer (CH) or between the source line (SL) and the channel layer (CH), irrespective of a charge storage gate voltage needed to inject charge into a charge storage layer (EC) by a quantum tunneling effect. In accordance with the reduction in voltage(s) applied to the bit line (BL1) and the source line (SL), thickness of a first select gate insulating film (30) of the first select gate structure (5) and thickness of a second select gate insulating film (33) of the second select gate structure (6) are reduced. High-speed operation is achieved correspondingly. In accordance with the reduction in voltage(s) applied to the bit line (BL1) and the source line (SL), thickness of a gate insulating film of a field effect transistor in a peripheral circuit that controls a memory cell is reduced. The area of the peripheral circuit is reduced correspondingly.

摘要： In a non-volatile semiconductor memory device (1) according to the present invention, a capacitive sidewall insulating film (21) of a capacitive element (C1, C2) is made of a layer same as that of a sidewall spacer (13a, 13b) of a memory cell (2), the film qualities and thicknesses of which are adjusted mainly for breakdown voltage. The configuration leads to an improved breakdown voltage characteristic and a stabilized capacitor characteristic of the capacitive element (C1, C2). The non-volatile semiconductor memory device (1) does not need a conventionally needed power supply for achieving low voltage application to a capacitive element, thereby achieving a simplified and downsized configuration accordingly.

摘要： When a memory cell (MC) is downsized by reducing the distance between a drain region (12a) and a source region (12b) on the surface of a fin (S2) with a high impurity concentration inside the fin (S2), the shape of the fin (S2) can be set such that a potential difference between a memory gate electrode (MG) and the fin (S2) is reduced to suppress the occurrence of disturbance. Accordingly, the memory cell (MC) achieves downsizing and suppression of the occurrence of disturbance.
