IS45S16320D-6CTLA1 is one of the most popular memory chips developed by Integrated Silicon Solution Inc (ISSI). It is a 4 megabit synchronous 32-bit Dynamic Random Access Memory (DRAM) which is widely used in high performance industrial and automotive applications. This chip provides the highest levels of performance with higher data throughput for critical applications.
IS45S16320D-6CTLA1 is a synchronous DRAM (SDRAM) device designed to operate on a 32-bit wide data bus. It employs a multiplexed address/command interface and is provided in 54-pin TSOP2 and LQFP84 packages. It is organized as 65536x64bits and the data transfer is initiated by the falling edge of the clock (CK). Upon each rising edge of the clock, a new cycle is started which can either be a read, write, refresh, or precharge cycle. There is also an in-system programmable feature that allows the user to optimize the refresh counter for power savings.
The IS45S16320D-6CTLA1 is mainly used in high performance industrial and automotive applications where high speed, low voltage, and low power dissipation are required. It is also ideal for any type of application where fast data transfer is needed. It is mainly used in memory modules and embedded systems. One of the key features of the IS45S16320D-6CTLA1 is its low voltage, which allows it to be used in portable devices such as laptops and PDAs. It is also used in audio/video devices, networking switches, and storage systems.
In terms of its working principle, the IS45S16320D-6CTLA1 is a synchronous DRAM device that is designed to operate on a 32-bit wide data bus. It uses a multiplexed address/command structure, where read, write, refresh, and precharge cycles are initiated with the falling edge of the clock. The user also has the ability to optimize the refresh counter for power savings. On a read cycle, the least-significant bit of the row address is latched at the falling edge of the clock and the most-significant bit of the column address is latched at the rising edge of the clock, followed by the data access. On a write cycle, the least-significant bit of the row address is latched at the falling edge of the clock, followed by the most-significant bit of the column address and the write data. Refresh cycles are initiated with the falling edge of the clock and precharge cycles initiated with the rising edge of the clock.
