SYSTEMS AND METHODS FOR WRITING TO HIGH-CAPACITY MEMORY

摘要

Systems and methods for writing to high-capacity memory are disclosed. In high-capacity memory systems in which the capacity of the characteristic portion of the memory (e.g., a page of NAND flash memory) exceeds the capacity of a buffer used to write to the memory, underutilization issues are prevalent. Data organized in the buffer can be combined with additional data to improve utilization of the characteristic portion. According to various embodiments, the additional data can include duplicate copies of the data, whitened data, or any other suitable type of data.

主权项

1. A method for writing to high-capacity memory, the method comprising:
receiving a request to write data from a host to a characteristic portion of a nonvolatile memory (“NVM”); determining that a capacity of a host buffer is less than or equal to half of a capacity of the characteristic portion; transferring the data from the host buffer to an NVM package component; and programming the data and at least one duplicate of the data to the characteristic portion.
