Abstract :
This paper proposes 7T SRAM which realizes block-level simultaneous copying feature. The proposed SRAM can be used for data transfer between local memories such as checkpoint data storage and transactional memory. The 1-Mb SRAM is comprised of 32-kb blocks, in which 16-kb data can be copied in 33.3 ns at 1.2V. The proposed scheme reduces energy consumption in copying by 92.7% compared to the conventional read-modify-write manner.
