    摘要: A bit error corrector includes an aging bit pattern memory operable to store at least one aging bit pattern which conveys aging-related effects within a succession of uncorrected bit patterns, a bit pattern modifier operable to modify a current, uncorrected bit pattern using the at least one aging bit pattern and generate a modified bit pattern, and a bit pattern comparator operable to compare the current uncorrected bit pattern with a corrected bit pattern which is based on the modified bit pattern and determine a corresponding comparative bit pattern. An aging bit pattern determiner is operable to recursively determine a new aging bit pattern based on the at least one aging bit pattern and the comparative bit pattern, and store the new aging bit pattern in the aging bit pattern memory for use during modification of a subsequent uncorrected bit pattern by the bit pattern modifier.

    摘要: Device for generating random numbers having a pseudo random number generator, a memory and a sequential controller. The pseudo random number generator generates a deterministic random number sequence after an initialization using an initialization value. The memory stores initialization information, wherein the initialization information is derived from a true random number or corresponds to the true random number. The sequential controller initializes the pseudo random number generator at start-up using the initialization information or the information derived from the initialization information, stores an intermediate state of the pseudo random number generator or information derived from the intermediate state in the memory at a turn-off of the pseudo random number generator, and uses the intermediate state or the information derived from the intermediate state for an initialization of the pseudo random number generator at a renewed start-up.
