US 2025/0147673 A1 · Data Routing In Networked SSDs

Abstract

Instead of all the NAND memory having asynchronous independent plane read (AIPR) enabled, a system utilizes a master-SSD to route data to multiple client SSDs via a controller memory buffer (CMB) according to the underlying NAND hardware (HW) of each of the client SSDs. The master-SSD will also analyze the application data retrieval of the logical data that is to be routed. The system comprises SSDs with AIPR NAND circuitry and SSDs with non-AIPR NAND circuitry. The system further comprises the master-SSD that will route data to any of the SSDs in the system based on the data retrieval type (sequential or random). Each of the SSDs can be of a different type beyond the NAND chip, such as HW IPs or specific firmware (FW) that is tuned towards specific data routing and retrieval requirements.

Claims20

Dependent claims

A data storage device, comprising:

a memory device, wherein the memory device has a first location for storing data expected to be randomly read and a second location for storing data expected to be sequentially read;
and
a controller coupled to the memory device, wherein the controller is configured to:
receive a command to write data to the memory device;
classify the data based upon whether the data is expected to be sequentially read or randomly read;
and
write the data to the memory device in either the first location or the second location based upon the classification.
