WebbSome SSDs use magnetoresistive random-access memory (MRAM) for storing data. Cache or buffer. A flash-based SSD typically uses a small amount of DRAM as a volatile cache, similar to the buffers in hard disk drives. A directory of block placement and wear leveling data is also kept in the cache while the drive is operating. Webb2 mars 2024 · Because DRAM in the controller cannot be used for caching data read/written or address mapping table, I/O performance is unavoidably degraded. For DRAM-less SSDs with a Non-Volatile Memory Express (NVMe) interface, this problem can be alleviated by using the host memory buffer (HMB) feature of NVMe [ 9, 13 ].
