The invention relates to a memory device with stable self-refresh operation and an operating method thereof. An operating method of a memory device includes entering a self-refresh section; updating a count code by counting edges of the reference periodic signal; activating an operation control signal for a first time in response to the count code for a self-refresh section when the temperature application code has an initialization value; updating the temperature application code after activating the operation control signal for the first time; activating the operation control signal for a second time in response to the count code based on the updated temperature application code; exiting from the self-refresh section; and initializing the count code and the temperature application code. 本公开涉及具有稳定自刷新操作的存储器件及其操作方法。一种存储器件的操作方法，包括：进入自刷新区段；通过对参考周期信号的边沿进行计数来更新计数码；响应于计数码，针对温度应用码具有初始化值时的自刷新区段来第一次激活操作控制信号；在第一次激活操作控制信号之后更新温度应用码；基于更新的温度应用码，响应于计数码来第二次激活操作控制信号；从自刷新区段退出；以及初始化计数码和温度应用码。
