SRAM Verilog

SRAM, short for Static Random Access Memory, is a type of memory that retains data as long as power is supplied to it. Verilog is a hardware description language widely used in electronic design automation to model and simulate digital systems.

To implement an SRAM module in Verilog, you can define a module with input and output ports for address, data, read/write control signals, and power supply. Here's an example of a basic 1-bit SRAM module:

module sram_1bit (
  input wire clk,
  input wire enable,
  input wire write,
  input wire [7:0] address,
  input wire [7:0] data_in,
  output reg [7:0] data_out
);

  reg [7:0] memory [255:0]; // 256x8 memory array

  always @(posedge clk) begin
    if (enable) begin
      if (write)
        memory[address] <= data_in;
      else
        data_out <= memory[address];
    end
  end

endmodule

In this example, the SRAM module has a clock input (`clk`), an enable signal (`enable`) to enable the memory operation, a write signal (`write`) to select read or write operation, an address bus (`address`) to specify the memory location, a data input bus (`data_in`) for write operations, and a data output bus (`data_out`) for read operations.

The internal memory array is declared as `reg [7:0] memory [255:0]`, representing a 256x8 memory. The data is stored or retrieved from the memory array based on the control signals and address.

Note that this is a simplified example demonstrating the basic structure of an SRAM module in Verilog. In practice, you may need to add additional features like timing control, address decoding, and more robust error handling.
