[Question] How to calculate the size of repairing storage?
[Answer] To calculate the size of repair buffer, user can use following formula the get the number.
Here assumes user use the same repair memory type.
Buffer size = (RA[address bits] + RRE) x (Repair_row_No) x (repair memory instances)
Following example is 2 rows redundant memory, RRE# is enable bit. Address is 13 bits. So, every repairing memory buffer size is
Buffer size = RA[12:0] *2 + RRE * 2 bits = 28 bits
