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.
