Data Storage Device and Method for Dynamic Prediction of Random Read with Low Memory Consumption - A simplified explanation of the abstract
This abstract first appeared for US patent application 17838493 titled 'Data Storage Device and Method for Dynamic Prediction of Random Read with Low Memory Consumption
Simplified Explanation
The abstract describes a data storage device and method for predicting random read commands with low memory consumption. The device includes a volatile memory, a non-volatile memory, and a controller. The controller allocates space in the volatile memory for a history pattern matcher data structure used to predict next read commands. It determines the accuracy of the predictions and dynamically adjusts the space allocated in the volatile memory based on the accuracy.

Original Abstract Submitted
A data storage device and method for dynamic prediction of random read with low memory consumption are provided. In one embodiment, a data storage device comprises a volatile memory, a non-volatile memory, and a controller. The controller is configured to allocate an amount of space in the volatile memory for a history pattern matcher data structure used to predict next read commands from a host to read data stored in the non-volatile memory; determine an accuracy of the predicted next read commands; and based on the determined accuracy, dynamically allocate a different amount of space in the volatile memory for the history pattern matcher data structure. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
