The ZDRHP 6664-R is a synchronous access One-Time Programmable Memory (PROM) that serves as a drop-in replacement for the Intersil HS-6664 RH. This product utilizes hardened metal fuse-link technology, featuring high reliability, low power consumption, and strong upset immunity.

The ZDRHP28F256-R is an asynchronous access One-Time Programmable Memory (PROM) that serves as a drop-in replacement for the Aeroflex UT 28F256 LVQLE. This product utilizes hardened metal fuse-link technology, featuring high reliability, low power consumption, and strong upset immunity.

The ZDS512K8-R is a high-speed, low-power, and high-reliability CMOS Static Random Access Memory (SRAM) manufactured using a bulk silicon CMOS process. It has a capacity of 4 Mbit and requires only a single 3.3V power supply. The memory operates in an asynchronous mode.

The ZDS512K32-R / ZDS512K40-R are two low-power, radiation-hardened Static Random Access Memories (SRAM) that are drop-in replacements for the 3D Plus 3DSR 16M32 VS 4500 / 3DSR 20M40 VS 6507. They have a capacity of 16/20 Mbit, require only a single 3.3V power supply, and operate in an asynchronous mode.

The ZDSP512K40 RH / ZDSP1M40 RH is a high-speed, low-power, and radiation-hardened large-capacity CMOS Static Random Access Memory (SRAM) manufactured using a 40 nm CMOS process, with a capacity of 20 Mbit/40 Mbit. It operates in asynchronous mode and is configurable for single or dual power supply operation.

The ZDSP256K16 RH is a high-speed, low-power, and radiation-hardened static, large-capacity, random access, parallel memory (SRAM) manufactured using a 40 nm CMOS process, with a capacity of 4 Mbit. It operates in asynchronous mode with a single power supply.
