Gene memory is an important part of electronic cell

and the existing genes memory structure cannot take into account the reliability and hardware cost.A novel gene memory structure named partial-DNA cyclic memory was presented

and only part of the system's entire DNA was stored with correlated redundancy.The lost genes caused by faulty cells could be obtained through gene update according to the faulty cells' neighbor cells.The stored gene number is independent form the scale of embryonics array and target circuit

and can be set according to actual demand in design process.Theoretical analysis and simulation results show that the novel gene memory not only to achieve the embryonics array's functional differentiation and self-repair

but also reducing hardware overhead while keeping system reliability.The proposed gene memory can be used to design larger scale self-repair chip.
