The statement in the Gowin documentation that in the reading mode "READ_MODE=0" the output register is not used and the OCE signal is ignored is not confirmed by practice - if the OCE was left unconnected or connected to the constant network, then a change in output data was observed even with CE=0, as well as the absence of such at CE=1. Synchronizing CE and OCE helps and the memory works properly in complex systems such as RISC-V emulation and i8080 emulation (with 32K RAM and 16K BSRAM based ROM), but there is no theoretical basis for this fix, so it is a hack.
