摘要

a variant and professional; hrungsbeispiel of the invention provides a circuit and a method for reducing silent datenverf & auml; lschung in speicherarrays without eca & all, hung in the reading and schreibzugriffsdaten. an n bit parit & auml; tscodierer with an n bit speicherarray connected.when the n - bit array is described, the data that are used to write in the speicherarray, also used by the n bit parit & auml; tscodierer a parit & auml; tswert to produce. the parit & auml; tswert is stored in a latch.when the n - bit array is read, the current parit & auml; tswert of parit & auml; tscodierers the zustandsmaschine pr & auml; law. the zustandsmaschine compares the current value of the parit & auml; tscodierers with the value stored in the latch.if the parit & auml; tswerte, stored and monitored, and professional; bereinstimmen, shows the zustandsmaschine, & white; a datenverf & auml; lschung occurred can be.
