Abstract: FPGAs need on-chip SRAM memories to achieve fast access of data.However,the data width and depth of traditional SRAMs are customized and fixed,which cannot satisfy FPGA's configurable and high flexible application demands.An on-chip configurable SRAM is proposed and designed which can realized different data widths and depths by user's configuration.The configurable SRAM can be used in different applications which improves the disadvantage of traditional SRAMs and increases the utilization of storage resources to above 88.9%at different data widths.The simulation results show the read delay is 1.67 ns at SMIC 0.15μm processunderflow through mode.
