nRF51 RAM section size

[Chinook]

Do all revisions of nRF51 have the same 4kB RAM sections with separate RAM AHB slaves? The product specification clearly states that only for revision 3 chips.

Hi

The RAM documentation in nRF51822_PS v3.1, section 3.2.2. is specific for third revision and does not apply for second or first revision nRF51

Update 9.7.2015 For nRF51 revision 1 and 2, only one AHB slave is present

Sure, and that's why I'm asking. So what about the first and second revisions? Do they also have 4KB RAM sections? And are those sections independent AHB slaves? This is important as it allows to avoid conflicts between different AHB masters.
