"WebNov 29, 2012 · An on-chip RAM has a read bus which can only access one word in the memory, and changes on a clock edge. So builds the memory instead out of a bunch of LUTs. In that case, you can think of the memory as build from a 2D array of flip-flops, and now it can wire up to all the words. " - Fwft read mode

WebFeb 7, 2013 · Basically the D_out is valid when empty /= '1', and so read_en acts more like an ACK rather than an enable. In a normal fifo you have to assert read_en to get the d_word on the next clock.
