      sysMEM Memory
      The LatticeECP/EC family of devices contain a number of sysMEM Embedded Block RAM (EBR). The EBR con-
      sists of a 9-Kbit RAM, with dedicated input and output registers.
      sysMEM Memory Block
      The sysMEM block can implement single port, dual port or pseudo dual port memories. Each block can be used in
      a variety of depths and widths as shown in Table 2-6.
      Table 2-6. sysMEM Block Configurations
      Bus Size Matching
      All of the multi-port memory modes support different widths on each of the ports. The RAM bits are mapped LSB
      word 0 to MSB word 0, LSB word 1 to MSB word 1 and so on. Although the word size and number of words for
      each port varies, this mapping scheme applies to each port.
      RAM Initialization and ROM Operation
      If desired, the contents of the RAM can be pre-loaded during device con
      fi
      guration. By preloading the RAM block
      during the chip con
      fi
      guration cycle and disabling the write controls, the sysMEM block can also be utilized as a
      ROM.
