  • Flash- and ROM-memory
    Patent number: 8576603
    Abstract: Method for conversion of a Flash memory cell on a first semiconductor device to a ROM memory cell in a second semiconductor device, the first and second semiconductor device each being arranged on a semiconductor substrate and each comprising an identical device portion and an identical wiring scheme for wiring the device portion to the Flash memory cell and to the ROM memory cell, respectively; the Flash memory cell being made in non-volatile memory technology and comprising an access transistor and a floating transistor, the floating transistor comprising a floating gate and a control gate; the ROM memory cell being made in a baseline technology and comprising a single gate transistor, which method includes manipulating a layout of at least one baseline mask as used in the baseline technology; the manipulation including: incorporating into the layout of the at least one baseline mask a layout of the Flash memory cell, and converting the layout of the Flash memory cell to a layout of one ROM memory cell by e
