Abstract

Described herein is a multi-host computing system (200) having multiple host processors running different operating systems. The described multi-host computing system (200) comprises a multi-host NAND flash controller (202) to allow sharing of a NAND flash device (108) among the multiple host processors. The described multi-host NAND flash controller (202) may include host interaction components, host command switching logic (310), and NAND command logic (316) to enable sharing of the NAND flash device (108).
