How is a simple RAM implemented in Verilog?

module simple_ram (input clk, input [3:0] addr, input [7:0] data_in, input we, output reg [7:0] data_out); reg [7:0] ram [15:0]; always @(posedge clk) begin if (we) ram[addr] <= data_in; else data_out <= ram[addr]; end endmodule

module simple_ram (input clk, input [3:0] addr, output reg [7:0] data_out); reg [7:0] ram [15:0]; endmodule

reg [15:0] ram [7:0]; always @(posedge clk) begin if (we) ram[addr] <= data_in; end

always @(negedge clk) begin data_out <= ram[addr]; end

What is the difference between synchronous and asynchronous memory?

Synchronous memory is clock-driven and faster, while asynchronous memory operates independently of the clock and is generally slower.

Synchronous memory does not require a clock signal to function.

Synchronous memory is slower and operates independently of the clock.

Asynchronous memory is clock-driven and faster than synchronous memory.
