Memory, or RAM as it is commonly known, is an essential component of any computer system. It is used to temporarily store data and instructions that can be processed quickly and efficiently by the computer. In the context of this article, we will be discussing the CY7C13451G-100BZXE memory integrated circuit and its application field as well as its working principle.

This memory IC, the CY7C13451G-100BZXE, is a high-speed, low-power, single-channel dual-data-rate synchronous dynamic random access memory (SDRAM) designed for use in embedded applications. It has a data bus width of 64 bits and an address bus width of 38 bits, and is offered in an FBGA package. It is ideal for use in applications such as computer-on-modules, avionics systems, GPS navigation, and imaging equipment.

The CY7C13451G-100BZXE provides high capabilities and high-bandwidth operation in a minimal pin count. It features data throughput performance of up to 800 MHz, supports multiple operating voltages, and supports both “page mode” and “burst mode” capabilities via hardware. It also has the capability of offering up to 4 banks of memory, thus providing additional data storage capacity.

The working principle behind the CY7C13451G-100BZXE works by taking in address and data information from the processor, constantly refreshing it and then providing the stored information back to the processor as soon as it is needed. This memory IC is built in a couple of ways. It uses either SRAM or DRAMS for the internal bits and is built by a wide range of manufacturers.

The behind-the-scenes hardware in the CY7C13451G-100BZXE comprises banks of memory cells arranged in rows and columns, with each cell capable of storing one bit of information. The SDRAM controller reads and writes data to each memory cell. The controller also handles read and write requests from the processor and controls the refresh cycles, which are necessary to maintain data integrity. The processor sends out an address, which is decoded by an address decoder within the controller. This determines which memory cell is being accessed and the data is read or written accordingly. The data is then provided to the processor.

The controller also handles the requests for refresh cycles which are necessary to maintain data integrity. Refresh cycles are registered by the controller in a two step process. First, the controller sends out a ‘refresh enable’ signal which ‘opens’ all the memory cells. This is followed by a ‘refresh enable’ signal which refreshes or rewrites all the data in the memory cell. This process is repeated at predetermined intervals.

Overall, the CY7C13451G-100BZXE is a powerful memory IC with a wide range of capabilities and features for embedded applications. It is a reliable and durable memory IC that is ideal for use in applications such as computer-on-modules, avionics systems, GPS navigation, and imaging equipment.
