Can RAM be visited in two modes?

[mhytr]

For instance,a 1248bit RAM.The 8 bit cpu visits it in a 156*8 mode,and a coprocessor wants to visit in a 4*132 mode(read or write 132bit at a time) .
Is it possible?
How it is implemented?

Hi,
Just add an HAL (abstraction layer) and write two functions that provide this features. One function reads in the format you want and other writes. This shouls not be a problem.
