Design of 3D NAND flash memory on-chip control logic circuit

This paper presents an implementation based on MCU as the control logic circuit for 3D NAND Flash. The proposed circuit has passed functional verification in simulation environment and been synthesized by Design Compiler. Its area is 0.35mm², and the dynamic power consumption is 7.52mW at 33MHz operating frequency. Compared with the traditional design, control logic circuit based on MCU is easier to be modified, which can greatly reduce the tape out cost of the upgraded product and shorten upgrade cycle by approximately 50%.
