Memory is an important component in the electronic system, and can be divided into two types: SRAM and DRAM. In order to meet the increasing demand for memory, the CY7C2564XV18-366BZC is no longer exclusive to DRAM, but is also used at the same time as SRAM. The CY7C2564XV18-366BZC is a memory chip that integrates both SRAM and DRAM in one chip.

In general, CY7C2564XV18-366BZC provides up to a maximum of 18 Mbit memory capacity in a single 40 pin package. Its operating voltage range is between 1.6V and 3.6V, and its operating temperature is between 0℃ and 85℃. CY7C2564XV18-366BZC is suitable for applications such as digital set-top box and tablet. As it has both SRAM and DRAM in one chip, it can boost system design capacity, reduce integration level, and reduce the complexity of system design.

The working principle of CY7C2564XV18-366BZC is that it requires two separate clock signals for accessing SRAM and DRAM, one is called SRAM clock and another called DRAM clock. Then, the memoy address bus is used to select either SRAM or DRAM to enable the access. The address and data are temporally stored in the internal registers before it is written in the memory. It reads and writes the data to and from the SRAM and DRAM according the address on the address bus.

In conclusion, CY7C2564XV18-366BZC has both SRAM and DRAM integrated. It applies to digital set-top boxes and tablet and has high capacity, a wide operating voltage and temperature range. Its working principle is made up of two separate clocks for accessing SRAM and DRAM, and data is temporally stored in the internal registers before it is written in the memory.
