New version of CTL Repair Syntax (Using Garys 8224 words x 14 bits Memory) S. Boutobza March 11 th.
Memory Architecture 8224 words, 14 bits, mux 16 Bit 0Bit 6Bit 7Bit 14 Rows 0 thru 511 Rows 512 and group of 8 spare columns (left half) 1 group of 8 spare columns (right half) 2 Spare rows (Bottom Bank) 2 Spare rows (Top Bank)
Spare Elements Any spare row in bottom bank can repair any row in the bottom bank Any spare row in the top bank can repair either of the rows (only 2) in the top bank Any group of 8 columns in left array can be repaired Any group of 8 columns in the right array can be repaired
CTL Syntax 1 st Syntax: - Uses the traditional map vector 0|1|r|x - Uses ValueRange to restrict the bits range 2 nd Syntax: - does not rely on ValueRange - use an interval format [TopRange..BottomRange]
