US Patent 7515490 Sensing circuit for organic memory

An organic memory at least includes a number of select lines, a number of data lines, a bit cell array, and a number of digital sensing circuits. The bit cell array includes a number of bit cells, wherein each bit cell includes an organic memory cell and a switch element. Each digital sensing circuit includes a current-to-voltage converter and a sensing block circuit. Therefore, a complete digital sensing mechanism of an organic memory IC is formed and is practicable and suitable for mass-production.
