Serial peripheral interface to multiple memory types

A method comprising:

• generating a map indicating a first set of addresses allocated to at least one first memory that implements random access and a second set of addresses allocated to at least one second memory that implements serial access;
• and
• in response to receiving a memory access request, selectively accessing the at least one first memory or the at least one second memory based on the map, wherein selectively accessing the at least one first memory or the at least one second memory comprises formatting a memory access request for either serial access or random access based on the map.

(canceled)

An apparatus comprising:

• at least one processing unit configured to generate a map indicating a first set of addresses allocated to at least one first memory that implements random access and a second set of addresses allocated to at least one second memory that implements serial access;
• and
• at least one controller circuit configured to access the at least one first memory or access the at least one second memory based on the map, wherein the at least one controller circuit is configured to access the at least one first memory by formatting a memory access request to the at least first one memory for parallel access and is configured to access the at least one second memory by formatting a memory access request to the at least one second memory for serial access.
