Abstract

This paper presents a dynamically reconfigurable SRAM array for low-power mobile multimedia application. The proposed structure use a lower voltage for cells storing low-order bits and a nominal voltage for cells storing higher order bits. The architecture allows reconfigure the number of bits in the low-voltage mode to change the error characteristics of the array in run-time. Simulations in pred...
