Memory - IS43R16160D-6BL Application Field and Working Principle

The IS43R16160D-6BL (hereafter referred to as the “device" or “IS43R”) is an integrated semiconductor memory pro-duced by International Rectifier. It is a 16-megabit, synchronous, dual-access, random access memory device(SDRAM) that is suitable for a variety of industrial and commercial applications. In this article, we will discussthe application field and working principle of the IS43R16160D-6BL.

Application Field

The IS43R is a single RAM device that is suitable for a variety of applications, ranging from general purposeembedded applications to gaming consoles and high-performance computing systems. It is a low-voltage, low-power-consumption device, making it ideal for portable devices that require long battery life. The IS43R has amaximum operating frequency of 150MHz, a maximum random access time of 15ns, and maximum interfacebandwidth of up to 6.4GB/s. It also features an industry-standard JEDEC-compliant SDRAM low-powerarchitecture, making it suitable for a wide range of applications.

The IS43R is also suitable for high-performance computing applications, such as server and workstationapplications. It has a wide range of high-performance features, including a 4-way interleaved architecturethat enables quick access of data. Additionally, the device offers support for single-cycle burst access at full-rated frequency, hi-speed pipelined operations with no wait states, and an array of error detection andcorrection features. In summary, the IS43R has the necessary features to provide high-performance yet low-power operation in a variety of embedded and computing applications.

Working Principle

The IS43R is a synchronous dynamic RAM device that uses a bank addressing mechanism to provideconcurrent, randomly accessible data access. The device is designed to be interfaced with buses such as theHigh-speed Uncomplicated Odd/Even Byte Connected bus, or HUB-9. The IS43R addresses a single 16-bit word at a time and transfers it to a 16-bit data bus, allowing processor-level concurrent access.

The device is powered by a single 2.5V supply, and the power can be distributed using an internal gatingstructure to minimize active power consumption. The device also features an internal auto-refresh counter,which reduces refresh access overhead as well as refresh period. The device can also be set for burst modeaccess, which allows data to be read or written in a single operation.

The IS43R also features an array of error detection and correction features, such as parity and ECC. Theparity bits serve as a check to detect any data errors, while the ECC ensures the data accuracy. The devicealso supports a range of power-saving modes, including self-refresh and row access strobe (RAS)timeout.

In conclusion, the IS43R16160D-6BL is a 16-megabit, synchronous, dual-access, random access memorydevice (SDRAM) that can be used in a variety of embedded and computing applications. The device has amaximum operating frequency of 150MHz, a maximum random access time of 15ns, and maximum interfacebandwidth of up to 6.4GB/s. The device also has a wide range of power-saving features, making it ideal forportable applications. Furthermore, the device features an array of error detection and correction features,including parity and ECC.
