Taking a Closer Look at Embedded Memory Design
If you use an electronic device of any kind, you are almost certainly using a system with embedded memory. Embedded memory simply refers to memory systems that are inside of devices and incorporated into the larger operating system. When embedded memory designs are industrial grade, they are rugged enough to function in extreme operating conditions. There are multiple potential formats for embedded memory design, allowing developers and engineers to select the best fit for their products. Here are the facts you need to know about embedded memory design.
Volatile and Non-Volatile Memory
Embedded storage can contain both volatile and non-volatile memory—in other words, both temporary and persistent memory. In each case, data are stored in bits within the embedded memory, which itself is stored within the embedded operating system. The embedded memory system is partially controlled through the embedded operating system and partially through software that tells the CPU how to access data stored on the embedded memory chip. Together, these systems allow for read and write operations in embedded memory.
Embedded Flash Memory
Embedded memory in SSDs, or solid state drives, is usually flash memory. This means that there are no moving disks or mechanical parts that are used to store data, but rather that information is programmed and erased solely via electrical currents. This allows the embedded memory design to be faster and more agile than other forms of memory. It also makes it particularly ideal for use in industrial applications, since it can also be used in conditions with extreme temperatures or in which shock or vibration would make memory with mechanical parts unreliable.
Embedded Memory Design Capacities
Embedded memory is designed with a range of different capacities to meet the needs of different applications. Generally, SLC, or single-level cell, memory designs have the smallest capacities, because they can only store one bit of data per cell, but they are the most reliable. Other designs may have larger capacities, but are frequently designed for consumer—rather than industrial—use.
