How are embedded memory chips implemented?
For the storage industry, embedded memory chips are mainly commercialized in two ways:
1. ASIC technology realizes memory chips
ASIC (Application Specific Integrated Circuit) has been widely used in the storage and network industries. In addition to greatly improving system processing capabilities and accelerating product development, ASIC is more suitable for mass-produced products and completes standardized designs based on fixed needs.
In the storage industry, ASIC is usually used to implement certain functions of storage product technology, and is used as an accelerator, or to alleviate the overall system performance degradation caused by excessive load on the CPU caused by a large number of calculations of various optimization technologies.
2. FPGA technology implements memory chips
FPGA (field programmable gate array) is the highest level of application specific integrated circuits (ASIC). Compared with ASIC, FPGA can further shorten the design cycle, reduce design cost, and have higher design flexibility. When changes need to be made to a completed design, ASIC redesign time is typically measured in months, while FPGA redesign time is measured in hours. This gives FPGA a market response speed unmatched by other technology platforms.
The new generation of FPGA has excellent low energy consumption, fast and fast (most tools calculate in picoseconds to billionths of a second) characteristics. At the same time, manufacturers can reconfigure FPGA function modules and I/O modules, and can also program them online to achieve online system reconstruction.
This allows FPGAs to build a soft-core processor that is customized in real time based on computing tasks. Moreover, the FPGA function is not limited and can be a storage controller or a processor. The new generation of FPGA supports a variety of hardware, with programmable I/O, IP (intellectual property) and multi-processor cores. These comprehensive advantages make FPGA used by some storage manufacturers to develop full-featured products with embedded memory chip architecture.
Embedded memory chip technology mainly focuses on the application of enterprise-level storage systems, providing high-quality support for access performance, storage protocols, management platforms, storage media, and a variety of applications. With the rapid growth of data and the increasing importance of data to business, the data storage market is rapidly evolving. From DAS, NAS, SAN to virtual data centers and cloud computing, they all pose great challenges to traditional storage design capabilities.
