Narrative:
Aircraft X departed runway 36L at mem and called me on the departure east frequency at XA54 local time. Aircraft X route of flight meant that the pilot should have contacted departure west; according to the mem 7 departure procedures. I instructed aircraft X to contact departure west; and the aircraft did so without incident. These types of mistakes with the frequency assignments on the mem 7 departure take place numerous times each day. For example; 6.5 hours later at XG20 local time; aircraft Y departed runway 36C and contacted departure west when; according to their routing; the pilot should have contacted departure east. Again; the aircraft was switched to the correct frequency without incident; but if this is not addressed; this confusing departure procedure will cause a tragedy. I suggest that a) that the current chart for the mem 7 departure be simplified by removing clutter and making sure that key instructions are located on the chart in relation to their context or B) frequencys be assigned according to departure runway (for example: departing runways 18R/36L or 27; the departure frequency is 124.65; departing runways 18L/36R; 18C/36C; or 9; the departure frequency is 124.15 -- any changes to these guidelines will be made prior to the departure by mem tower).

Title: MEM DEPARTURE CONTROLLER REPORTS TWO INSTANCES OF FLT CREW CHECKING IN ON THE WRONG FREQUENCY ON THE MEM 7 SID.
Narrative: ACFT X DEPARTED RWY 36L AT MEM AND CALLED ME ON THE DEP EAST FREQ AT XA54 LOCAL TIME. ACFT X ROUTE OF FLT MEANT THAT THE PLT SHOULD HAVE CONTACTED DEP WEST; ACCORDING TO THE MEM 7 DEP PROCS. I INSTRUCTED ACFT X TO CONTACT DEP WEST; AND THE ACFT DID SO WITHOUT INCIDENT. THESE TYPES OF MISTAKES WITH THE FREQ ASSIGNMENTS ON THE MEM 7 DEP TAKE PLACE NUMEROUS TIMES EACH DAY. FOR EXAMPLE; 6.5 HOURS LATER AT XG20 LOCAL TIME; ACFT Y DEPARTED RWY 36C AND CONTACTED DEP WEST WHEN; ACCORDING TO THEIR ROUTING; THE PLT SHOULD HAVE CONTACTED DEP EAST. AGAIN; THE ACFT WAS SWITCHED TO THE CORRECT FREQ WITHOUT INCIDENT; BUT IF THIS IS NOT ADDRESSED; THIS CONFUSING DEP PROC WILL CAUSE A TRAGEDY. I SUGGEST THAT A) THAT THE CURRENT CHART FOR THE MEM 7 DEP BE SIMPLIFIED BY REMOVING CLUTTER AND MAKING SURE THAT KEY INSTRUCTIONS ARE LOCATED ON THE CHART IN RELATION TO THEIR CONTEXT OR B) FREQS BE ASSIGNED ACCORDING TO DEP RWY (FOR EXAMPLE: DEPARTING RWYS 18R/36L OR 27; THE DEP FREQ IS 124.65; DEPARTING RWYS 18L/36R; 18C/36C; OR 9; THE DEP FREQ IS 124.15 -- ANY CHANGES TO THESE GUIDELINES WILL BE MADE PRIOR TO THE DEP BY MEM TWR).
