Design of a Logic-in-Memory Multiple-Valued Reconfigurable VLSI Based on a Bit-Serial Packet Data Transfer Scheme

A new packet data transfer scheme (PDTS) is introduced to reduce a configuration/control memory (CCM) size of a multiple-valued dynamic reconfigurable VLSI based on a logic-in-memory architecture. In the PDTS, the CCM size for memory access is proportional not to the number of distributed memory modules in the reconfigurable VLSI, but to the number of read operations in all the memories. Thus, remarkable reduction of the CCM size can be achieved in comparison with the conventional control scheme. Moreover, the PDTS contributes to fine-grain ON/OFF control of the current sources in Differential-Pair Circuits (DPCs) utilizing flag information which indicates whether the data is valid or invalid.
