Does 'zeros' overwrite existing memory or alocate new memory and replace adress?

I have a matrix inside a handle class, that needs to be reset to zero from time to time. Does
A=zeros(size(A))
replace the matrix adress with a new adress? If so, is alocating new memory faster than reseting existing memeory?
Thank you.

To set all elements of an existing array A to zero, A(:)= 0 is recommended (and faster).
