    CY7C1472BV25 SRAM Chip Migration

              Hello. I'm planning to use multiple CY7C1472BV25 SRAM chips at my design (an Arbitrary Waveform Generator) and I want to migrate them, so that they take up less I/O pins of my FPGA. According to the datasheet, there are two NC pins, the NC(288) and the NC(144) that "they are used for expansion to the 144M and 288M densities". Does anyone know how those pins work? How exactly does this migration (expansion) takes place?   
      Thank you,
