3D NAND Flash的片上控制逻辑电路设计

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

    摘要
  • 摘要: 本文设计并实现了基于MCU的控制逻辑电路, 并在仿真环境下进行了功能验证, 用Design Compiler完成逻辑综合.结果表明, MCU工作正常, 所占面积为0.35 mm2, 在33 MHz的工作频率下动态功耗为7.52 mW, 符合设计目标.与传统的控制逻辑电路相比, 基于MCU的控制逻辑电路具有更高的可修改灵活性, 极大降低了升级产品的流片成本, 缩短控制逻辑电路设计更新周期约50%.

     

    Abstract: 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%.
