am using this 64k x 16 Cypress SRAM in my qsys design and able to use my nios code in it. I presume the size of this ram is 1 Mbit ie 128 Kbyte but am able to use only 64 Kbyte of the memory. I am using the IDR71V416 memory available in QSYS lib and changed it to 16 bit address and 16 bit data lines. I observe that its allocating 2^16 address locations with 16 bit data bus but my NIOS code during build shows as if only 64 Kbyte of memory is available. Please help asap.
