QDR-II+ memories can perform read and write operation in parallel but internally memory cell can execute a single operation (Read or Write) at the time. So we are considering the worst case which is 50% read and 50% write for internal memory array.
Cypress does not specify Idd values based on different reads and writes operation ratio as there is a distribution associated with the same. However, we focus on the worst case situation (Idd max) so that we can guarantee Idd (MAX) values.
I understand that 50-50% usage specified in note 24 is related to the internal memory operation, not to its external interfaces.
I'll consider the values specified for Idd as the worst possible consumption.
Thanks for that quick answer.
