      Memory Cascading
      Larger and deeper blocks of RAMs can be created using EBR sysMEM Blocks. Typically, the Lattice design tools
      cascade memory transparently, based on speci
      fi
      c design inputs.
      Single, Dual and Pseudo-Dual Port Modes
      Figure 2-15 shows the four basic memory con
      fi
      gurations and their input/output names. In all the sysMEM RAM
      modes the input data and address for the ports are registered at the input of the memory array. The output data of
      the memory is optionally registered at the output.
      Figure 2-15. sysMEM EBR Primitives
      The EBR memory supports three forms of write behavior for single port or dual port operation:

      – data on the output appears only during read cycle. During a write cycle, the data (at the current

      Write Through
      – a copy of the input data appears at the output of the same port, during a write cycle.
      3.
      Read-Before-Write
      – when new data is being written, the old content of the address appears at the output.
      Memory Core Reset
      The memory array in the EBR utilizes latches at the A and B output ports. These latches can be reset asynchro-
      nously or synchronously. RSTA and RSTB are local signals, which reset the output latches associated with Port A
      and Port B respectively. The Global Reset (GSRN) signal resets both ports. The output data latches and associated
      resets for both ports are as shown in Figure 2-16.
