CONTENT ADDRESSABLE MEMORY

摘要

PURPOSE: A content addressable memory is provided to reduce power consumption by preventing power from being supplied to memory blocks which are not used. CONSTITUTION: A spin MOSFET pair includes a first spin MOSFET(40) and a second spin MOSFET(50) which is connected in parallel to the first spin MOSFET. The magnetization states of the first and second spin MOSFETs are set according to memory data. A first wire applies a gate voltage to conduct one of the first and second spin MOSFETs according to search data. A second wire applies currents to the first and second MOSFETs.
