TRANSLATION LAYER PARTITIONED BETWEEN HOST AND CONTROLLER

摘要

A method for using a partitioned flash transition layer is disclosed. Step (A) receives, at an apparatus from a host, a write command having first write data. Step (B) generates second write data by compressing the first write data in the apparatus. The second write data generally has a variable size. Step (C) stores the second write data at a physical location in a nonvolatile memory. The physical location is a next unwritten location. Step (D) returns, from the apparatus to the host in response to the write command, an indication of the physical location.

1. A method for using a partitioned flash transition layer, comprising the steps of:
(A) receiving, at an apparatus from a host, a write command having first write data; (B) generating second write data by compressing said first write data in said apparatus, wherein said second write data has a variable size; (C) storing said second write data at a physical location in a nonvolatile memory, wherein said physical location is a next unwritten location; and (D) returning, from said apparatus to said host in response to said write command, an indication of said physical location.
