+This VCI target is an embedded SRAM controller. It is actually a simplified version of the !VciRam component, and provide the same services : it handles one or several
 independent memory segments. Each segment is defined by a base address and a size (number of bytes).
 Both the base and the size parameters must be multiple of 4.

+The segments allocated to a given instance of this component must be defined in the [wiki:Component/MappingTable Mapping Table]. The segments are implemented as dynamically allocated arrays in the constructor.
 
-Each segment is implemented as a dynamically allocated array in the constructor.
+This component supports an - optionnal - latency parameter, defining the RAM access latency.
+A zero value for this parameter corresponfd to a bsic one cycle latency.
