Optimal Memory Tests Coding for Programmable BIST Architecture
(ХНУРЭ, 2008) Ivaniuk, A. A.
Programmable memory BIST architecture is becoming a necessity for embedded memory cores. Classical memory BIST architectures use fixed algorithmic tests during the whole live of digital device. To improve the flexibility of memory BIST the programmable solution, based on finite state machine with microcode control, was invented. The requirement to use such flexibility is dictated by reason to use newest test for memory cores. In this paper a new Programmable Memory BIST architecture with small microcode memory is proposed. The analysis of existing March tests allows to code them into the optimal binary format, which cause not only small hardware overhead but also may speed-up the transferring of new test over the serial interfaces like IEEE 1149.1 and P1500.
