sysMEM Memory
LatticeECP2/M devices contains a number of sysMEM Embedded Block RAM (EBR). The EBR consists of an 18-
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. FIFOs can be implemented in sysMEM EBR blocks by imple-
menting support logic with PFUs. The EBR block facilitates parity checking by supporting an optional parity bit for
each data byte. EBR blocks provide byte-enable support for configurations with18-bit and 36-bit data widths.
