March Algorithm
The March algorithm tests SRAM memory by filling all its entries test patterns It carries out several passes through an SRAM checking the patterns and writing new patterns. The SRAM read and write operations performed on each pass are called a March element and each element is repeated for each entry [1] [2]. The March algorithm is often used to find functional faults in SRAM during testing [3].
The March Algorithm detects Stuck-At faults and some Transition Faults
Mach C-
Mach C- is a less robust variant of the March algorithm that detects Address and Coupling faults, but it is significantly faster.
