You forgot to mention in which of the three worlds you live: PSoC 1, PSoC3 or PSoC5.
for PSoC3 a solution could be:
CYXDATA char MyMem[1 ] _at_ 0x2000;
and later on:
Sorry, the above post lacks some information.
This should work for PSoC3 and 5
CYXDATA *MyMem = (void *)0x2000; // With initialization
