Abstract

A method and a circuit are given, to implement and realize power saving Sense Electronics Endowed (SEE) memory using modified memory read cycles, named as Smart Memory Readout (SMR). In an SMR-mode read cycle, the memory is only active a small fraction of a clock cycle thus saving power. In this small fraction where the memory is enabled by SMR-mode read, the memory content is read to a shadow register and held until read by the microcontroller. Said circuit and method are designed in order to be implemented with a very economic number of components, capable to be realized with modern integrated circuit technologies.
