Linear Flash PC Card – Series 100
MagicRAM’s Series-100 Flash memory card family conforms to the PCMCIA / JEIDA international standard but with word (16 bit) operation only. Without the complicated control logic circuit and attribute memory design, it is the low-cost version of the MagicRAM’s Series 5 Flash memory card family.
With the flexible power supply design in this card family, user can choose single 5V Vcc or dual power supply (Vcc and Vpp). Choosing the dual power supply, user can also choose 5V or 12V as the Vpp supply voltage flexibly.
Like the Series 5 Flash memory card family consisting of multiple Intel’s 28F008S5 (or 28F016S5), this card family also maintains backwards-compatibility with the MagicRAM’s Series 2 Flash memory card family which consist of Intel’s 28F008SA Flash memory devices.
Key enhancements include : 1) smart voltage allows Vpp to be 5V or 12V, 12V option renders the faster block erase, program performance. 2) enhanced suspend capabilities. 3) in-system block locking. This series Flash memory cards contain 16, 32, 64 or 128 independent 64K-word blocks. Each block can be individually erasable.
To reduce the attribute memory cost overhead, the Card Information Structure (CIS) is stored in Block of the flash memory array. In embedded applications, the CIS may not be required by the system and the entire flash memory array can be used by the system.
