Following table only show area of MBIST and MBISR and enable full function diagnosis only.
Therefore, the area’s increasing rate is higher than expectation.
Note:
a. MBIST function with MARCH C+ and full function diagnosis
b. MBIST and MBISR function with MARCH C+ , 2 ROW redundancy memory and hard-repair solutions (APB interface)
c. MBIST and MBISR function with MARCH C+, 2 ROW redundancy memory, hard-repair solutions (APB interface) and full function diagnosis
The second comparisons show the MBIST area statistics in 16KB memory size. Normally, the MBIST and MBISR’s area increasing rate are 3% to 12% to whole memory of SoC.
SRAM(1024x128) 27322.5225 (nm2)
Note:
a. MBIST function with MARCH C+ and full function diagnosis
b. MBIST and MBISR function with MARCH C+ and 2 ROW redundancy memory
c. MBIST and MBISR function with MARCH C+, 2 ROW redundancy memory and full function diagnosis
