Abstract
Oggetto dell'invenzione è un sistema per l'uso di memorie dinamiche a semiconduttore aventi locazioni difettose, in cui tali memorie vengono inizialmente organizzate in banchi per formare una parola di informazione elementare e quindi vengono identificate tutte le locazioni omologhe di indirizzo che non sono affette da errori così da ottenere una mappatura, la quale viene memorizzata in una memoria non volatile (OTP) associata al banco di memoria, per dar luogo ad una tabella di transcodificazione; ed in cui l'utilizzatore esterno che deve recuperare i dati contenuti nei blocchi della memoria accederà a detta memoria non volatile (OTP) utilizzando degli indirizzi di memoria consecutivi (logici) forniti ad esso da una sezione intelligente del sistema. e recupererà da essa degli indirizzi transcodificati (fisici) che gli permetteranno di accedere direttamente ed immediatamente a detti blocchi di memoria.Nel sistema secondo l'invenzione, per ampliare il numero delle locazioni in cui sia possibile memorizzare informazioni, utilizzando anche zone affette da limitata difettosità, si applicano tecniche mirate alla applicazione per la correzione dell'errore (ECC).
