Abstract
Oppfinnelsen angår en fremgangsmåte og apparat til kontroll av skriving til et dataminne. Apparatet omfatter kontroll- organer (1-8) for dannelsen av et data- minneaktiveringssignal CE som svar på benyttelsen av en forutbestemt tallkode til kontrollorganene. Kontrollorganene omfatter en tidsstyringskrets 2 som startes ved å anvende en tallkode og som ___ hindrer dannelsen av dataminne- aktiveringssignalet CE når en forut- bestemt tid har gått fra anvendelsen av tallkoden. For forsering av skrivingen av lange datablokker inn i et dataminne, kjennetegnes oppfinnelsen ved at kontrollorganene videre omfatter organer (3,5,6) for omstart av koblingsorganet (2) innenfor et forutbestemt tids- intervall fra benyttelsen av tallkoden eller den tidligere dataminneskriveopera- sjonen som et resultat av en utfort dataminneskriveoperasjon.
