• Manufacturer Part Number: ml2500b
• Description: Analog-storage Single-chip Record/playback With Bit-cell Flash Memory
• Manufacturer: Oki Optical Components

Addressable Memory Space for Recording
The total memory space of the ML2500B is divided into 4 blocks, 256 K bit-cell for each block, and a block is
divided into 80 sectors, 3.2 K bit-cell for each sector. Finally, a sector is divided into 16 pages, 200 bit-cell for
each page.
A12 to A11 are assigned to represent a block address, A10 to A4 to represent a sector address, and A3 to A0 to
represent a page address.
