INHERENT ADAPTIVE TRIMMING

摘要

A memory system may use adaptive trimming to control throughput and traffic from the host to/from the memory. The trimming parameters of memory may be adaptively changed based on the data rate from the host. The programming speed may be slowed in order to reduce wear and improve endurance. In particular, the data rate for the transfer of data from a data buffer to the memory (e.g. NAND flash) may be matched to the host data rate. This programming speed reduction may be triggered upon prediction of idle times in the host bus.

主权项

1. A method for adaptive trimming on flash memory, the method comprising:
receiving write commands from a host; detecting write traffic throughput from the host to a memory buffer; and trimming a traffic throughput from the memory buffer to the flash memory based on the detected write traffic throughput and based on the received write commands.
