Abstract
A fault tolerant queue system for selecting storing positions in a memory for performing write operations from an on-line maintained idle list of addresses to free storing positions in the memory and for calculating addresses for collecting data earlier stored in the memory. The storing positions are exposed to a testing procedure. The testing procedure is performed periodically on each storing position in idle cycles during operation of the system, and the result is used to maintain the idle list. The addresses selected for testing are released from system use as controlled by the system.
