| description | A computer implemented method and data processing system for providing a hardware controlled one-time write for fiscal printers. A signal from a fiscal printer is received at a memory controller in an electronic journal or fiscal memory card. The signal comprises transaction data and an address in a memory space in the electronic journal or fiscal memory card. The memory controller checks a marker bit corresponding to the address to determine if the marker bit is in a written state. Responsive to a determination that the marker bit is not in a written state, the memory controller sets the marker bit to the written state. The memory controller then writes the transaction data to the address in the memory space. |
