The EDF8164A3PD-GD-F-D is a kind of 64K x 4-bit Dynamic Random Access Memory (DRAM). It is a leading non-volatile memory solution that provides superior performance and increased data security due to its inherent immunity to unintended data loss caused by power interruptions, voltage variations, and other external conditions.

This type of DRAM can be used in a variety of applications, such as computers, networking applications, digital audio, digital video equipment, digital cameras, GPS devices, and other digital hardware. In addition, DRAM is also used to store important customer data and application settings in both consumer and industrial products. It can also be used in automotive applications and medical devices.

The typical working principle of the EDF8164A3PD-GD-F-D is based on a capacitor-static random access memory (SRAM) structure. It uses a cell matrix that is arranged in a two-dimensional array of capacitors and transistors. Each capacitor stores one bit of data, and the transistors are used to control the flow of data and information between the cells and other parts of the memory module. The data is stored in the form of charge in each capacitor.

The DRAM is read and written to by applying electrical signals to its cells. When a read operation is performed, the capacitor charges will be transferred externally as a voltage level that contains the value stored in the cell. In the write operation, the capacitor charge is changed depending on the new bit that is being written to the cell. Each cell has an individual address, and the data is accessed by passing an address code to the memory module.

In order to protect the data stored in the DRAM, it is necessary to periodically refresh the charge of the capacitor. This task is usually performed by an external memory controller which keeps track of the data stored in each cell and refreshes it at a predetermined interval. Depending on the application, different refresh patterns can be used such as static, partial and full bursts.

Overall, the EDF8164A3PD-GD-F-D is a powerful and reliable DRAM that can be used for a variety of applications. It has a fast access time, is extremely energy efficient and provides additional data security due to its inherent immunity to power interruptions and external conditions.
