This dir is where the vendor specific Verilog memory model should be
stored.
The memory used is the Microchip
23K640 a 64kbit,
SPI-connected serial SRAM.
The Verilog memory model can be downloaded from that webpage or by
clicking on this link.
Download and unzip the file in this directory. This should produce two
files, 23A640.v and 23K640.v. The one needed for simulation is 23K640.v
