#Instruction-pipeline Data hazard between two consecutive memory access instruction
Although the following instructions do not make much sense but if such case occurs, is data forwarding from MA of I1 to MA of I2 allowed? Or will it result in some stall? ... //A<-Mem[address]I2: Store Adress2, A // Mem[Address2] <- A

Hazard in Pipeline
I know this question is already asked,But here my doubt is different, I have seen many people calculating the RAW hazard without seeing the no of stages in the pipeline ... 2 after the SUB finishes.
