The semiconductor memory device converts a sequentially-changing step voltage into a current so as to provide a write current, and minimizes the influence of a threshold voltage variation caused by fabrication deviation, such that it can be stably operated. The semiconductor memory device includes a current driver. The current driver includes a step voltage provider configured to provide a step control voltage sequentially changing in response to a pulse control signal, a control current provider configured to provide a control current in response to the step control voltage, and a write driver configured to provide a write current capable of writing data in a memory cell in response to the control current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device","description":"A semiconductor memory device is disclosed.
