Abstract [sv]

Detta examensarbetet har gått ut på att konstruera ROM-minnen med liten effektförbrukning.Genom att vi undersökt olika geometriska strukturer i form av kolumnuppdelning så har simuleringsresultaten visat god geometri med liten strömförbrukning. Därefter har minnesarean delats in i olika block med den valda geometrin där endast det blocket som är adresserat aktiveras dvs när blocken är i passiva läge drar de ej ström. Blockindelning och kolumnuppdelning kontrolleras av de mest signifikanta bitarna i adressen.

Abstract [en]

In this thesis we have designed and developed a static ROM with low power consumption.Through examining different geometrical structures by splitting up the columns in the memory array we have, through computer simulation, found the best geometry with respect to power dissipation. In addition we have partitioned the memory array into several blocks with the optimal geometry, enabling us to switch off the memory blocks not beeing addressed and thereby lowering the power consumption even further. The column and block partitioning is controlled by the most significant address bits.
