    Abstract: Quantum memory is a crucial device for the storage and retrieval of photonic quantum states, serving as a cornerstone for quantum communication, quantum computing, and quantum metrology. Significant progress has been achieved in various physical systems and storage protocols. Among these, warm atomic ensembles have garnered considerable attention due to their inherent advantages, including room-temperature operation, low preparation cost, and strong light-atom interactions. Raman quantum memory protocol stands out for its suitability in high-speed quantum information processing, offering broad bandwidth and effective storage of ultrashort pulses. This review focuses on recent progresses in quantum memory based on warm atomic ensembles employing Raman protocol. We introduced key performance metrics of quantum memory, elaborated on the principles and characteristics of the Raman protocol, and summarized the latest theoretical and experimental advancements, as well as discussed the future research prospects.
