Abstract
A system and method are provided for using a system-on-chip (SoC) memory manager to dynamically shutdown and restart an off-chip memory module. After determining that a memory switch is to be enacted, an SoC memory switching core asserts a hold on processor operations. The memory switching core transfers data from a source memory module to a destination memory module. In a shutdown operation, data is transferred from a first memory module source to an external second memory module destination interfaced to the memory switching core. In a restart operation, data is transferred from the second memory module source to the first memory module destination. The memory switching core uses a memory map for translating the data addresses in the source memory module to data addresses in the destination memory module. Then, the memory switching core deasserts the hold on processor operations.
