Abstract

Apparatus and methods disclose techniques to control access to a memory array. The memory array can be accessed by either a first interface or a second interface. A switch register grants privilege levels, which control access. For example, a high privilege level can grant access and a low privilege level can deny access. A status register indicates when an interface with a high privilege level is busy accessing the memory array.
