    PSRAM  is dynamic RAM with built-in refresh and address-control circuitry to make it behave similarly to static RAM (SRAM). It combines the high density of DRAM with the ease of use of true SRAM. PSRAM (made by Numonyx) is used in the Apple iPhone and other embedded systems such as XFlar Platform.
    Some DRAM components have a "self-refresh mode". While this involves much of the same logic that is needed for pseudo-static operation, this mode is often equivalent to a standby mode. It is provided primarily to allow a system to suspend operation of its DRAM controller to save power without losing data stored in DRAM, rather not to allow operation without a separate DRAM controller as is the case with PSRAM.
 
ISSIISSI is a technology leader that designs, develops, and markets high performance integrated circuits for the following key markets: (i) automotive, (ii) communications, (iii) digital consumer, and (iv) industrial and medical. Our primary products are high speed and low power SRAM and low and medium density DRAM. The Company also designs and markets NOR flash products and high performance analog and mixed signal integrated circuits. We target high-growth markets with our cost-effective, high-quality semiconductor products and seek to build long-term relationships with our customers. We have been a committed long-term supplier of memory products, including lower density and smaller volume products, even through periods of tight manufacturing capacity.
