In the single-port RAM configuration, the outputs can only be in
read-during-write mode, which means that during the write operation,
data written to the RAM flows through to the RAM outputs. When the
output registers are bypassed, the new data is available on the rising edge
of the same clock cycle it was written on. For more information about
read-during-write mode, see

Implementing Simple Dual-Port Mode
Simple dual-port memory supports a simultaneous read and write.
