Host managed solid state drivecaching using dynamic write acceleration

An apparatus comprising:

• a substrate;
• and
• logic coupled to the substrate, wherein the logic is implemented in one or more of configurable logic or fixed-functionality hardware logic, the logic coupled to the substrate to:
• write a block of data addressed within a fast NVM region into a dynamic single cell buffer region under the control of a host computer;
• write a block of data addressed outside the fast NVM region into a static single level cell buffer region;
• and
• automatically write the contents of the static single level cell buffer region into a dynamic multi-level NVM media region;
• wherein the fast NVM region comprises a set of dynamic single level NVM cells within the dynamic multi-level NVM media region addressable under the control of the host computer, and
• wherein the multi-level NVM cells are dynamically convertible into and from single NVM cells.

A method comprising:

• writing a block of data addressed within a fast NVM region into a set of multi-level NVM cells organized into a dynamic single level cell buffer region under the control of a host computer;
• writing a block of data addressed outside the fast NVM region into the set of multi-level NVM cells organized into a static single level cell buffer region;
• and
• automatically writing the contents of the static single level cell buffer region into a dynamic multi-level NVM media region;
• wherein the fast NVM region comprises a set of dynamic single level NVM cells within the dynamic multi-level NVM media region addressable under the control of the host computer, and
• wherein the multi-level NVM cells are dynamically convertible into and from single NVM cells.
