FRAM GX85RS2MC (Compatible with MB85RS2MT) for speech recognition scenarios

Language recognition involves uploading speech to a big data cloud platform through the network, which analyzes and translates the speech data through algorithms and speech data, and finally sends it down to the terminal devices through the network. Since the time of uploading and downloading speech data is affected by the network quality, there will be uncertain network latency. In addition, this scheme also has information security problems, partly used for not wanting to upload voice data to the network.

Therefore, the network latency effect and information security problem can be solved by applying GXSC ferroelectric memory GX85RS2MC. Ordinary memories record data based on the presence or absence of an electric charge in the internal storage area, and the recorded data is read and analyzed by scanning the change in the amount of electric charge generated inside the memory from the outside; ferroelectric memories record data by using a phenomenon known as “polarization,” in which the molecular orientation of a material is changed by an electric field, and it is difficult to analyze and steal the recorded data by using this phenomenon. This phenomenon makes it difficult to analyze and steal recorded data.

The GX85RS2MC ferroelectric memory is suitable for storing weight matrices for AI algorithms because of its high-speed writing and high read/write counts. In addition, the large-capacity ferroelectric memory can store a variety of speech algorithms and data, which in turn can be used to complete speech recognition functions locally.

GX85RS2MC products are described as follows:

1, the memory cell can be used for 1E6 read/write operations*1, data retention: 10 years @ 85°C (200 years @ 25°C), no data loss after system power down.

2、Made by ferroelectric process and silicon gate CMOS process technology, the chip does not need a battery to keep the data, can improve the security of data.

3, the maximum power consumption of 5mA, standby current is only 7μA, can effectively reduce the power consumption of the system.

4, support for SPI serial interface, the maximum 25MHz operating frequency, can meet the needs of the main control chip fast communication.

5, the operating temperature range is -40 ℃ to 85 ℃, in line with the industrial environment of the application.

6, the use of SOP8 small package, saving PCB board design space, easy to layout.

7, Performance is compatible with Fujitsu‘s MB85RS2MT, and the price advantage of GX85RS2MC is much higher than MB85RS2MT.
