Method and device for refreshing the memory content of a memory cell of a read-only memory |
摘要 |
A method and a device for refreshing the memory content of at least one memory cell of a read-only memory is described. An embodiment of the present invention involves determining the instantaneous charge status of the memory cell; comparing the instantaneous charge status of the memory cell with a charge threshold (U_schw) which is greater than the reading charge (U_erh) sufficient for correct detection of the memory content of the memory cell; and raising the charge status of the memory cell if the instantaneous charge status of the memory cell is below the charge threshold (U_schw).
