generally the hardware is designed such that the main CPU/microcontroller has access to a system memory bus, connected to a physical memory device. and CPU instructions are normally taken from this main mem. but if u are interested in accessing any peripheral's memory - sometimes that is possible. Eg, PCI devices, by manipulating with the PCI registers (which mapped to the main memory via DMA) it is possible to access the PCI memory, and may be storing contents that survive rebooting of the computer. Search for PCI rootkit via Google: http://www.ngssoftware.com/research/papers/Implementing_And_Detecting_A_PCI_Rootkit.pdf is just an example. So for your case: how do u specifically store/extract contents on that SRAM meant for "buffering" purposes only? if that is possible then just extract from that memory into main memory for execution.
