Table 1–4. Unsupported Features for the QDR II and QDR II+ SRAM Controllers with UniPHY
Altera has carried out extensive random, directed tests with functional test coverage
using industry-standard models to ensure the functionality of the QDR II and QDR
II+ SRAM controllers with UniPHY.
Reduced controller latency
Read latency
Maximum data width
ODT (in memory device)
x36 emulation mode
Notes for
(1) The maximum achievable clock rate when reduced controller latency is selected must be attained through
