DS42515 is a storage device that is under development by AMD. The product is powered by 3.0V and has a maximum access time of 85ns. The operating temperature range is -25°C to +85°C. The product features simultaneous read/write, zero latency, secure storage, and zero power operation.
The AMD Am29DL164D is a 16 megabit, 3.0 volt-only stacked multi-chip package (MCP) device that combines a 16 Mbit flash memory with a 4 Mbit static RAM (SRAM). The device is organized as 1,048,576 words of 16 bits each or 2,097,152 bytes of 8 bits each and is available in a 69-ball FBGA package.
Key features include simultaneous read/write operations with zero latency between banks, allowing a host system to program or erase one bank while reading from the other. The device incorporates a Secured Silicon (SecSi) sector for secure storage and utilizes AMD-supplied Data Management Software (DMS) to facilitate EEPROM emulation and simplify system design.

The device is organized as 1,048,576 words of 16 bits each or 2,097,152 bytes of 8 bits each.
It allows a host system to program or erase in one bank and immediately read from the other bank with zero latency.
It is an extra 64 KByte sector that can be factory locked to store a secure Electronic Serial Number (ESN) or customer lockable for bonus space.
