Understanding and Building Fuse Box interface

Fuse Controller Interface

Embedded memories occupy a sizable percentage of area in modern-day SOCs. As memories are designed within very strict boundaries of technology, they are more prone to errors. So repairable memories have become very popular in today's design. As the number of memories increases, there is a need to build a solid infrastructure to facilitate repair functionality. With the increasing density of repairable memories, fuse box has also become a crucial part of the infrastructure to store the repair data.

The bad:

While the customer has the freedom to choose any fuse IP he
wants from the market, there is no underlying standard interface these
IP operate in. Hence it is the responsibility of the user to create a
fuse box interface that is capable of providing a good handshake
between the pins of a fuse controller and the non-volatile fuse IP.

The good:

Tessent MemoryBIST solution provides a generic fuse box
interface along with a fuse box that can be utilized by the user for
evaluation & experimentation. There is a readily available interface
for TSMC nodes.

In this session:

Let's have a look into Tessent fusebox controller
protocol and understand the fusebox interface development &
verification process.

This webinar will explain the challenges in building a fuse controller
interface which is a key component of repair implementation in today’s
industrial designs.
