lpm_ram_dp Megafunction

Parameterized dual-port RAM megafunction. This megafunction is provided only for backward compatibility; instead, Altera recommends using the altsyncram megafunction. The lpm_ram_dp function uses DFFE primitives or latch arrays in MAX3000 and MAX7000 devices or if the USE_EAB parameter is set to "OFF". If you need extra features, you can use the altdpram megafunction. Altera strongly recommends using synchronous rather than asynchronous RAM functions.

Note:
  • The Quartus® Prime Standard Edition Compiler automatically implements this function in logic cells in MAX3000 and MAX7000 devices.
  • You can use the Assignment Editor to add, change, or delete assignments and assignment values for megafunctions.
Note: More information is available on the lpm_ram_dp megafunction on the Altera website.
