Semiconductor storage device and method of throttling performance of the same

摘要

A semiconductor storage device (SSD) and a method of throttling performance of the SSD are provided. The method can include includes gathering at least two workload data items related with to a workload of the semiconductor storage device, estimating the workload using the at least two workload data items, and throttling the performance of the semiconductor storage device according to the estimated workload. Accordingly, a workload that the semiconductor storage device will undergo can be estimated.

1. A method of maximizing the lifetime of a semiconductor storage device (SSD), the method comprising:
collecting data corresponding to workload commands received by the SSD; operating the SSD according to respective ones of the workload commands received; estimating a workload of the SSD based on the collected data; and calculating a delay to be applied to next workload commands received by the SSD based on the estimated workload, wherein the estimating the workload is performed when a predetermined amount of data is collected and the delay is realized by at least one of controlling a speed of a clock signal applied to an element of the SSD and inserting an idle time between a first operation of the SSD and a second operation of the SSD, each of the first operation and the second operation including one of a read operation and a write operation.
