Latency reduction using stream cache

A method comprising:

• receiving a request to access a data block in a memory device from a host system;
• determining that the data block stored in a first buffer in a host memory is related to a set of one or more data blocks stored at the memory device;
• and
• storing the set of one or more data blocks in a second buffer in the host memory, wherein the first buffer is controlled by the host system and the second buffer is controlled by a memory sub-system.

A non-transitory computer readable medium including instructions, which when performed by a computer system comprising a memory device, and a processing device operatively coupled to the memory device, cause the computer system to perform operations comprising:

• receiving a request to access a data block in the memory device from a host system;
• determining that the data block stored in a first buffer in a host memory is related to a set of one or more data blocks stored at the memory device;
• and
• storing the set of one or more data blocks in a second buffer in the host memory, wherein the first buffer is controlled by the host system and the second buffer is controlled by a memory sub-system.
