Abstract:
1. A digital sensing circuit used for sensing bit information stored in a bit cell of an organic memory, comprising: a current-to-voltage converter, having a current terminal, used to convert a conduction current flowing through the current terminal into a voltage signal according to the conduction current; a sensing block circuit, coupled to the current-to-voltage converter and used to receive the voltage signal, so as to buffer and output the bit information stored in the bit cell according to the voltage signal; and a reset block circuit coupled to the current-to-voltage converter, wherein the reset block circuit is used to reset the voltage signal according to a first switch signal; and wherein the current-to-voltage converter comprises: a first transistor, with a first source/drain of the first transistor being connected to the current terminal of the current-to-voltage converter, with a gate of the first transistor being connected to a second switch signal; and a capacitor, with a first terminal and a second terminal, wherein the first terminal is connected to a second source/drain of the first transistor; the second terminal is connected to a first potential; and the voltage signal is obtained via the first terminal; wherein the reset block circuit comprises: a second transistor, with a first source/drain of the second transistor being connected to the first terminal of the capacitor, with a second source/drain of the second transistor being connected to a second potential, with a gate of the second transistor being connected to the first switch signal, wherein, when the first transistor is conducted, the second transistor is not conducted; and when the first transistor is not conducted, the second transistor is conducted.
